Welcome to the forums, hope you enjoy it here
I’d recommend checking out Kimetsu no Yaiba (Demon Slayer). There’s also a fairly obscure shonen called Buso Renkin where the 2 MCs seemed to have a relationship similar to Ichigo & Rukia.
Sone other series you might enjoy based on the favourites you listed: Danganronpa, The Ones Within, Gleipnir & The Promised Neverland.
