My brother recently got into Demon Slayer so I wanted to make a kny oc for him since I did it before with both me and my sister and never got around to my brother :)
But I started by refreshing my own design because wow?? It’s been 4 years since I first made my kny insert character and a lot of things are now outdated! Not to mention my art has improved a lot, I hope. More details under the cut!
Meet Ebisu Koharu: youngest of the Ebisu family and physically the weakest. They only barely passed Final Selection by hiding for the entire week and surviving off tips from their older siblings. Nonetheless, they still want to contribute, which is why they hold onto a thick, leather bound book that records every demon they’ve ever met in precise detail, with labeled diagrams and scribbled calculations in the margins of different strengths and weaknesses.
After spending a few years on the job, and properly seeing their data contribute to the successes of other demon slayers, they’ve come a bit more into their own as a competent researcher and fighter, though they still do tend to request paired missions with friends and family to act more as a support role rather than a fighter.
The Ebisu family is one of scholars. The eldest daughter Kaoru is a doctor, and the eldest son Shougen is a chemist. By nature, fighting is not necessarily their strong suit, which is why their family breathing style and techniques are all poison-assisted. Of the three, Koharu is the weakest and most averse to combat— they wield a short half-length blade, with more of a smooth ceremonial hilt and sheath than any practical weapon.

What We Learned from Flying a Helicopter on Mars
The Ingenuity Mars Helicopter made history – not only as the first aircraft to perform powered, controlled flight on another world – but also for exceeding expectations, pushing the limits, and setting the stage for future NASA aerial exploration of other worlds.
Built as a technology demonstration designed to perform up to five experimental test flights over 30 days, Ingenuity performed flight operations from the Martian surface for almost three years. The helicopter ended its mission on Jan. 25, 2024, after sustaining damage to its rotor blades during its 72nd flight.
So, what did we learn from this small but mighty helicopter?
We can fly rotorcraft in the thin atmosphere of other planets.
Ingenuity proved that powered, controlled flight is possible on other worlds when it took to the Martian skies for the first time on April 19, 2021.
Flying on planets like Mars is no easy feat: The Red Planet has a significantly lower gravity – one-third that of Earth’s – and an extremely thin atmosphere, with only 1% the pressure at the surface compared to our planet. This means there are relatively few air molecules with which Ingenuity’s two 4-foot-wide (1.2-meter-wide) rotor blades can interact to achieve flight.
Ingenuity performed several flights dedicated to understanding key aerodynamic effects and how they interact with the structure and control system of the helicopter, providing us with a treasure-trove of data on how aircraft fly in the Martian atmosphere.
Now, we can use this knowledge to directly improve performance and reduce risk on future planetary aerial vehicles.
Creative solutions and “ingenuity” kept the helicopter flying longer than expected.
Over an extended mission that lasted for almost 1,000 Martian days (more than 33 times longer than originally planned), Ingenuity was upgraded with the ability to autonomously choose landing sites in treacherous terrain, dealt with a dead sensor, dusted itself off after dust storms, operated from 48 different airfields, performed three emergency landings, and survived a frigid Martian winter.
Fun fact: To keep costs low, the helicopter contained many off-the-shelf-commercial parts from the smartphone industry - parts that had never been tested in deep space. Those parts also surpassed expectations, proving durable throughout Ingenuity’s extended mission, and can inform future budget-conscious hardware solutions.
There is value in adding an aerial dimension to interplanetary surface missions.
Ingenuity traveled to Mars on the belly of the Perseverance rover, which served as the communications relay for Ingenuity and, therefore, was its constant companion. The helicopter also proved itself a helpful scout to the rover.
After its initial five flights in 2021, Ingenuity transitioned to an “operations demonstration,” serving as Perseverance’s eyes in the sky as it scouted science targets, potential rover routes, and inaccessible features, while also capturing stereo images for digital elevation maps.
Airborne assets like Ingenuity unlock a new dimension of exploration on Mars that we did not yet have – providing more pixels per meter of resolution for imaging than an orbiter and exploring locations a rover cannot reach.
Tech demos can pay off big time.
Ingenuity was flown as a technology demonstration payload on the Mars 2020 mission, and was a high risk, high reward, low-cost endeavor that paid off big. The data collected by the helicopter will be analyzed for years to come and will benefit future Mars and other planetary missions.
Just as the Sojourner rover led to the MER-class (Spirit and Opportunity) rovers, and the MSL-class (Curiosity and Perseverance) rovers, the team believes Ingenuity’s success will lead to future fleets of aircraft at Mars.
In general, NASA’s Technology Demonstration Missions test and advance new technologies, and then transition those capabilities to NASA missions, industry, and other government agencies. Chosen technologies are thoroughly ground- and flight-tested in relevant operating environments — reducing risks to future flight missions, gaining operational heritage and continuing NASA’s long history as a technological leader.
You can fall in love with robots on another planet.
Following in the tracks of beloved Martian rovers, the Ingenuity Mars Helicopter built up a worldwide fanbase. The Ingenuity team and public awaited every single flight with anticipation, awe, humor, and hope.

so here's our list from last night. I added a couple more things because, well, scam-related things came up. by which I mean I finally got an email back from them.
Do dishes
Clean catbox
Sweep floors
Clean up sewing stuff (upstairs and downstairs)
Assemble air mattress, etc.
Clean up papers next to coffee table
Breakfast: can be from sbux because they’re giving you extra points
Text scone: zoom?
Apply for jobs friend sent you
Plug in computer so you actually can apply for those jobs
open dispute with credit company for scam
i mean maybe actually find an attorney to write me a letter of representation and demand, or at least gird myself to do so if the dispute doesn't work (and I feel like it might not, which fucking sucks)
I guess it's 1:10 PM and I should perhaps eat something. dad's flight was delayed an hour, but I'll leave earlier than I plan to for the airport because it's only coming from san jose and they always try to fly fast to make up time (and inevitably it works, but I don't know how much they'll be able to make up in, like, a 45-min flight).
okay self. eat. then do whatever. idgaf. but maybe i WILL gaf about something after I've eaten. ugh.
either that or my brain really did curdle last night and this is just how shitty icky curdled brain feels rn

Green energy is in its heyday.
Renewable energy sources now account for 22% of the nation’s electricity, and solar has skyrocketed eight times over in the last decade. This spring in California, wind, water, and solar power energy sources exceeded expectations, accounting for an average of 61.5 percent of the state's electricity demand across 52 days.
But green energy has a lithium problem. Lithium batteries control more than 90% of the global grid battery storage market.
That’s not just cell phones, laptops, electric toothbrushes, and tools. Scooters, e-bikes, hybrids, and electric vehicles all rely on rechargeable lithium batteries to get going.
Fortunately, this past week, Natron Energy launched its first-ever commercial-scale production of sodium-ion batteries in the U.S.
“Sodium-ion batteries offer a unique alternative to lithium-ion, with higher power, faster recharge, longer lifecycle and a completely safe and stable chemistry,” said Colin Wessells — Natron Founder and Co-CEO — at the kick-off event in Michigan.
The new sodium-ion batteries charge and discharge at rates 10 times faster than lithium-ion, with an estimated lifespan of 50,000 cycles.
Wessells said that using sodium as a primary mineral alternative eliminates industry-wide issues of worker negligence, geopolitical disruption, and the “questionable environmental impacts” inextricably linked to lithium mining.
“The electrification of our economy is dependent on the development and production of new, innovative energy storage solutions,” Wessells said.
Why are sodium batteries a better alternative to lithium?
The birth and death cycle of lithium is shadowed in environmental destruction. The process of extracting lithium pollutes the water, air, and soil, and when it’s eventually discarded, the flammable batteries are prone to bursting into flames and burning out in landfills.
There’s also a human cost. Lithium-ion materials like cobalt and nickel are not only harder to source and procure, but their supply chains are also overwhelmingly attributed to hazardous working conditions and child labor law violations.
Sodium, on the other hand, is estimated to be 1,000 times more abundant in the earth’s crust than lithium.
“Unlike lithium, sodium can be produced from an abundant material: salt,” engineer Casey Crownhart wrote in the MIT Technology Review. “Because the raw ingredients are cheap and widely available, there’s potential for sodium-ion batteries to be significantly less expensive than their lithium-ion counterparts if more companies start making more of them.”
What will these batteries be used for?
Right now, Natron has its focus set on AI models and data storage centers, which consume hefty amounts of energy. In 2023, the MIT Technology Review reported that one AI model can emit more than 626,00 pounds of carbon dioxide equivalent.
“We expect our battery solutions will be used to power the explosive growth in data centers used for Artificial Intelligence,” said Wendell Brooks, co-CEO of Natron.
“With the start of commercial-scale production here in Michigan, we are well-positioned to capitalize on the growing demand for efficient, safe, and reliable battery energy storage.”
The fast-charging energy alternative also has limitless potential on a consumer level, and Natron is eying telecommunications and EV fast-charging once it begins servicing AI data storage centers in June.
On a larger scale, sodium-ion batteries could radically change the manufacturing and production sectors — from housing energy to lower electricity costs in warehouses, to charging backup stations and powering electric vehicles, trucks, forklifts, and so on.
“I founded Natron because we saw climate change as the defining problem of our time,” Wessells said. “We believe batteries have a role to play.”

Basically. I got screwed.
I am very sorry for how relatively quiet this blog has been but I've been dealing with a very unpleasant situation the last few months, and now I need help.
Essentially, I tried to help someone out, and she took advantage of me, and I have no way to recoup my losses.
Earlier this year, I moved into a new house. Before we sold the old house, a Now-Former friend ran into some trouble and was about to become homeless with pets and a small child. Not wanting them to be on the street, we offered to hold off selling the old house so she could stay there for a little while, if she could pay the cost of the mortgage on that house (because I could afford one mortgage but not two) while we helped her find somewhere more permanent.
I was not making money from this- since I was still paying the utilities and property taxes, I was actually losing money, but willing to soak that in order to help her save up and get her on her feet.
Instead, she:
Never Paid a Dime towards covering the mortgage costs like she agreed ($12,000 for the nine months she was there)
Trashed the house ($500 dump fees for the trash alone)
Let her pets piss and shit all over the house ($1,500 bio hazard cleanup, $4000 to replace the carpet and other damaged flooring)
Caused an electrical issue in the garage ($900 to repair)
Broke the washer, dryer and refrigerator ($2500 to replace)
Broke the fence ($1000 to repair)
When I told her I could no longer financially support her and that I needed to sell the old house, she illegally squatted there for a solid three months and I had to hire a lawyer and actually take her to court to get her to leave ($2,500)
The resulting stress has been, as you can imagine, stressful.
So stressful, in fact, that it aggravated a the medical conditions my husband had and made him extremely sick. He had to go to the hospital and take time off work to recover. Now the health insurance is trying to weasel out of paying his short-term disability claim.
So net, this woman has managed to cost me around $25,000 and that's not taking into account the missed paychecks and medical expenses. I do not have $25,000, and until at least $13,000 of that is spent to repair the damage she did, I legally cannot sell the house to even begin to recoup my losses.
Theoretically, I could sue this woman, but she doesn't have any money and it would be me paying even more money I don't have to get... Nothing. So I'm asking for help to cover the costs of getting the old house ready to sell, my husband's medical expenses, and other expenses incurred by this debacle:
If you can help out in any way-share, donate spare change, anything- I'd be extremely grateful.
Thank you.
