#ALSO ALTERNATIVELY. SAME AGE AU BUT BC OF TIME TRAVEL SHENANNIGANS

[phantompages]

Same Age AUs are so fascinating to me, and of the ones I've seen I really like them. In particular if we have Reigen and Shigeo both as middle schoolers because instead of an older mentor figure Shigeo is ending up with another kid. He gets to have a friend his age who gets to drag him around to do stuff and it's nice, really nice to have a friend he can relate to. Meanwhile Reigen has soooo many ✨issues✨ but hey he's great at bullshitting and is getting Shige to open up some more, while on the flip side he's also getting a friend and can go out and do more now that he has someone to do stuff with. Plus they make great business partners so this is going amazingly :D

Another version I like is if this is the result of some time travel shenanigans, mostly because I like seeing a more stark contrast between kid Reigen and adult Reigen, especially through Shigeo's eyes because... this isn't his shishou, not exactly, because kid Reigen doesn't have the years of life experience that helps his words hold more meaning, even if kid Reigen is still a great talker and bullshitter. He can't say everything right that Shige needs to hear and its a bit off putting, especially if kid Reigen has different views on being "special" and whatnot (considering... "I want to be someone"). But there's still elements there that is just so Reigen in the way he talks and the way he moves that its like. Yeah, this is a kid, but it's the same person and everyone can see just how Reigen is, this is how he started. He's not Shigeo's shishou but he's still Reigen.
