Chiryokumaru

Inside a majestic museum, a young warrior gets attacked by shadow beasts born from people's fear and uncertainty over what they don't know. The warrior fights against them using the energy charger on his waist, but soon the energy runs out. In this desperate situation, he finds a new, unexpected power. Youtube Note: the short was created for the Japan Kanji Aptitude Testing Public Interest Foundation (Nihon Kanji Nouryoku Kentei Kyoukai) to promote the Japan Kanji Aptitude Test (Nihon Kanji Nouryoku Kentei, or "Kanken").
