>>39930727Anon, cosplaying at "that" level is never for fun. Like the 3D Live for the Holo girls, it is almost always a self funded endeavor to peddle their warez, be it photobooks, OF / Patreon / Fanbox exclusive content, merch or similar for profit activities.
Comiket is the biggest showcase for their work and they usual spend half the year getting ready for the 2 days it last because the whole intented market will be looking at that.
