/jp/ - Otaku Culture

I've been making some connections between the Atelier Kaguya games, and I'm starting to think they might be part of a larger interconnected universe, like a multiverse.
The spa where the protagonist of 新妻ふわトロ癒やらしエステ works seems to be the same one where the protagonist of 異世界Hィートマッサージ dies and gets isekai’d along with the entire building because both spas have the same name. However, I can't remember for the life of me if that isekai world ever has its name mentioned.
If it turns out to be this Aeon world mentioned in Pure x Holic, then that would link these games with the xHolic series and maybe 異世界モンムスセンセーション as well.
