No, it's not Casper and it's not a ghost.

Warashi-kun (童くん) is the main character of the Anchor Manga Warashi-kun series of comic strips from the Triggerheart Extension fan corner of the japanese Arcadia magazine. The Friendly Ghost Warashi-kun tells us some funny short stories about the Triggerhearts, and sometimes he gets involved in some situations like meeting Exelica.


The character's name comes from the company who created the Shienryu series, Sengeki Striker and Triggerheart Exelica, but for some reason it wasn't used as their mascot.
