@HajimeteNHK Since he has his own massage parlour, it's possible one of his customers mentioned a girl who think she's so good at giving massages. The MC wanted to pay a visit to show the girl the height of the Heaven and the depth of the Earth.
@RPWPA So, you think he went there for that but just forgot all about it due to his professional pride? He has zero shyness and is very blunt, though, so you'd think he would have done it if that was his intention. When he first appeared, I actually thought he went there for human experimentation, with zero intention to have sex. But then again, with his personality, you never know.
Just so anyone who is interested, don't massage the spine bones, you can very easily cripple the person... unless that is your goal... you do you I'm just a random stranger
