A quick look Tifa Lockhart as Makoto Niijima's Queen mesh-mod, part of this collab project of re-imagining persona 5 characters with Final Fantasy 7 Remake look, next step is trying to mod it into the game.
Look. Makoto Niijima is my favorite character in P5, but she doesn't have ownership of that name. Besides Makoto Yuki was named first once the P3 movies come but we got a lot of people who wouldn't acknowledge and prefer the manga one so they stuck with Minato, and that isn't a problem. They can choose what they what but his canon name is Makoto Yuki. Minato Arisato was the manga's only name and he has a different personality than Yuki's personality.
And here is a person who counters the above comment. Two people can't have the same name in the same series.
Is not farfetched for people to have the same name, and besides Makoto Yuki is still currently a seal for Humanity. The odds of them meeting outside of the PQ games are non-existent at this point. You know I don't think it was mentioned they have the same name in PQ2, because it's a very common unisex name. But if you can't honestly tell the difference, One is a boy, the other is a girl, one is born in 1992-1993, and the other was born in 1998. One is older and the other younger, one last name is Yuki, and the other is Niijima, you can call them by their last name, as the p3 cast called him Yuki a lot.
And Atlus isn't brand new with reusing names being a very common name in Japan, like Minato.
