Tokiwa Kitareri (トキワ来たれり!!, Tokiwa Kitareri!!) is a Japanese manga by Syun Matsuena serialized in the weekly manga magazine Shōnen Sunday since December 2014. Following the conclusion of Matsuena's previous work, Kenichi: The Mightiest Disciple, three one-shot chapters were released, introducing the main characters before the serialization properly began.
