I remember mentioning Aruto and Izu from Zero-One as recurring characters in the same vein as Mitsuru, not to mention having Rise (Persona 4), Ikutski Aoi and Tsubasa Oribe (Tokyo Mirage Sessions) showing up for a few episodes.

Other than that, I guess the last ones we could add are the main trio from Kamen Rider Yuugo (Yugo, Shinichiro, and Mayu) since they would be connected to Seiza and Alex in a way. One thing I do think would be a good scene are the Manga Hero Cures beign shocked to find out that Alex is a Rider despite his age
