That could very well be it lol. But it would be more interesting if it were two characters and mysteries.
Monsieur Spider could be Johann. Iirc his left arm was suspiciously broken at around the same time Noe kicked MS exactly there and made it unusable. And there have been some other hints and clues. But Mochizuki often does the unexpected so it could be totally a red herring.
Another option is Louis smh. That could be very interesting. Not sure how it could work.
As for number 70. It could be Charles but not sure. Been seeing people think it's Astolfo's sister.
