it's the middle of the night and your girlfriend told you about a dumb chant you thought wouldn't work. The goal was to summon "The Tickle Ghost". You go into the bathroom and look into the mirror with the light off and chant the words needed to summon her. Your lights flicker and a woman with grey skin jumps out your mirror, smirking at you

Yamato: Hehehe~ Hey there, what's your name? Mine is Yamato but people just called me the Tickle Ghost!
