Yakiimo Handsome Saitou

Mysterious monsters attack the people of Japan, but heroes are there to protect them with powers that run on a rate of yen per second. For Hiasa Sen however, there are much more important things to worry about, like catching sales on groceries, his many part time jobs and most importantly, taking care of his little sister. When danger approaches however, he has a secret power of his own, but it may be more trouble than it's worth.

One day, high schooler Kaito Kuji lost his memory. When he came to, he found the word "Thank you" written on his chest above a dial for a capsule toy vending machine. It's a mysterious capsule toy vending machine, which contains his lost memories and also some special supernatural abilities. But in order for him to turn the dial, he has to have someone tell him, "Thank you"...?!! So he needs to gather people's gratitude and use the toy capsule machine to fight!!
