Most of the times, when a seiyuu has to voice their character after a quite period of time (of not voicing them), it can lead to number of problems. They usually require more time to remember the voice and the feeling they have when voicing their character. It can set back the recording time and definitely, make the seiyuu anxious and feel responsible for hindering staff and other seiyuu.
During [Free! Timeless Medley], luckily ^_^ it wasn’t Wing only who needs a lot of ‘tuning’. Hirakawa Daisuke (Ryugazaki Rei’s seiyuu) and Suzuki Tatsuhisa (Tachibana Makoto’s VA) were facing the same problem, so Wing didn’t need to do the ‘tuning’ alone *lol*
Hosoya also likes homemade food such as hijiki (sea vegetable) simmer in soy paste, okra (another vegetable), and grilled fish. He said he can eat three bowls of rice with them XD
Women in Japan usually lives quite long (85 years old in average), so it is pretty much possible that Hosoya’s grandma is still alive ^^/
Chris maybe the character that has the most ad-lib lines from his seiyuu :) although sadly those lines got cut out ^_^; too R-18 XD? Yasumoto Hiroki wears glasses and seldom uses contacts. He really invested in portraying Chris as much as he can.
