Set on an alternative Earth, Superheroes are celebrities and a high rating TV show rates their achievements, awarding them points until an annual King of Heroes is crowned. Old-school hero Wild Tiger is assigned a new partner with very different views on the heroes role in society but soon a vigilante criminal presents them with a serious problem.

The world's number one assassin has been reincarnated as the eldest son of a family of aristocrat assassins. In exchange for being reincarnated in another world, a goddess has imposed upon him one condition. "Kill the Hero who is prophesied to destroy the world." This was to be the mission in his new life. The synergistic effect of the vast knowledge and experience he gained that made all manner of assassinations possible in the modern world, and the secret techniques and magic of the fantasy world's most powerful family of assassins turn him into the greatest assassin of all time.

As master assassin Usui Yuen looks into a series of assassinations made on the grand samurai clan, the Satsuma, he encounters Kurima Raizo, member and survivor of one of the attacks. Together, they discover the true nature of these murders is bigger than over stolen resources. As they get closer to the truth, will they come out alive to exact revenge?

Maru is convinced that there will be a boy there who looks exactly like him.
