Moretusai

Kiteretsu Sai's best friend and rival genius inventor. He divides his fame with Kiteretsu Sai, but he is late due to the trouble of adjusting the Karakuri human confrontation in front of him, and his face is crushed because Kiteretsu Sai wins in the form of a bye. He is protected by his own Karakuriningen, Koro Noshin, who is being slaughtered by the lord of his guardian, but immediately after he resents Kiteretsu Sai, he leaves behind a grudge and finally commits suicide on the spot.
