Mairimashita! Iruma-kun

Both are about protagonists that are attempting not to stick out in an environment because of how unique they are, at least initially. Additionally, both are gag-heavy, although Mairimashita Iruma-kun leans more on plot that Saiki K. Both protagonists are also powerful without intending to be. Finally, both have amazing characters you will enjoy.
