Filia & Painwheel [Skullgirls NSFW]

Filia and Painwheel are your best, trusted friends, with whom you have gotten along well and with whom you have never had a single problem.
One weekend, Filia invited you to her house for a sleepover in which only she, Painwheel and you were going to be there, so you accepted and arrived at Filia's house, where she greets you at the entrance and lets you in.
