1. After you rescue Nanako and Mimiko and black out a little in the inn, Geto will asked about your condition. There's an option, don't choose the resist option.
2. After you stay the night at Geto's place, and you can't use your power, there's also an option after that. Don't choose the resist one again. [MINI SPOILER] you'll disappear right after that but just trust the process❤️
