During an ordinary fight Kai disappears and the ninja try everything to find him. But it’s like he just vanished. Only a small clue left at their family’s blacksmith shop gives Nya and Lloyd the mission of finding their missing brother. But what is in store for them is something they never expected.

Bakugo and Izuku's parents were killed in a home invasion, but who takes them in... Is someone no one expected.

Kai never suspected that looking at a sunset would cause him to get attacked by some stranger. But now he is faced with a lot more than some crazed man looking for a fight. Now he has to deal with an egoistic king, an elegant, but insane woman with super strength, an impossible maze, and a lost warrior connected to Sensei Wu and Cole. Yep, just another day for the ninja.
