Shihyakushiki

In the Edo period, there was an "ogre" that used "bugs" to possess people and take their lives. Momotaro, sent by the god to defeat the ogres, worked hard to exterminate the ogres with three of his subjects, but one day, they were confronted by a powerful ogre that threatened to annihilate them all. Momotaro went into a long, long sleep in order to accumulate the strength to defeat the ogres, but he awoke again in the age of 2025. Momotaro is reincarnated as a chick...!
