Kuwana Ikuo is a well known animator who has contributed a lot of distinct pieces of animation on a variety of projects, including popular TV-anime (FMA, Panty & Stocking, Wolfs Rain, Denno Coil, Eureka 7) and a number of big theatrical anime (Evangelion, Spriggan and Princess Mononoke). A graduate from Yoyogi Animation Academy, Ikuo’s industry origins are at studio Ghibli, although he didn’t have a lot of influence there. During that time, Ikuo forged a strong friendship with animator Yoshida Kenichi, who also started out at Ghibli, and it’s thought that it was this relationship that got him work on Eureka 7 and Overman King Gainer. It was Ikuo’s work on Eureka 7 that first got him recognition as a good animator, however it was his efforts for Street Fighter Alpha Generations (which he also directed) that elevated him into the limelight.
I really haven’t heard Ikuo mentioned much in the English-speaking fandom (or at all), and I admit I only really just heard of him (the above bio is based on the sakuga wiki). It’s always nice to learn about a new animator. I quite like his style, but I guess I need to watch Street Fighter Alpha Generations to really comment on him. Judging by this MAD, he has a really rough and visceral style, which comes through really well with the effect animation from Gurren Lagann, and works perfectly for the Wolfs Rain part. I’m not sure which studio he is currently affiliated with (or if he’s a freelancer), but he’s done a lot of work for GAINAX recently, so he’s probably with them.
