"Ayumu Igarashi" doesn't seem to appear in the staff rolls of any Koei games. There are two soundtrack albums that name appears on, Shin Sangokumusou 4 and Musou Orochi, and both of those games credit Ippo Igarashi as a sound editor (among many others). So I went ahead and hooked up Ayumu as an alias of Ippo.

I thought "Ayumu" might just have been an error and not an intentional alias, but it's printed in English and Japanese on SSM4, so it'd be a real bad mistake if so :V
