>>211871501 (OP)I don't think I'd ever get bored of heaven. The number of video games or isekai I'd try out would be infinitesimal. Hell I'd live in the Harry Potter world for multiple lifetimes, each time trying out different ways of living.
But in the context of the show, I mean it was an ending so they had to put some sort of thematic climax. Jason was implied to have tried out a plethora of different experiences in the magic portal door and even that he got bored of. The rest of the gang lived in heaven for hundreds of "years" before they started to get bored of it. Tahani was the only realistic character from that perspective, who likely got bored of perpetual pleasure and shifted to a creative fulfilling role, one that would keep her occupied as long as humans existed.
