It actually looks like some of the Contra: Hard Corps team plus Pachi and Endo. Cygames and CyDesignation staff are handling top level design (director, producer, character designer, composer etc.) while a team of mostly less prominent staff members seems to be doing the technial development on the ASW side. Hideyuki Anbe (Hard Corps director) and Hideaki Sawada (Hard Corps character designer) are working as Development Manager and Art Director, Kazuto Sekine (Pachi) is Battle Planner, and Ryohei Endo (Chronophantasma director, FighterZ planner) is Development Director.
Obviously they've all had pretty long involvement with ASW and Pachi and Endo were pro players, but I think as ASW continues to grow as a mercenary developer for other publishers, you're going to be seeing guys like Motomura and Anbe branch out and head up their own teams within the company.
