Daughter of the Emperor - Chapter 421

Based on the popular Vocaloid series, by HoneyWorks, called “Kokuhoku Yokou Renshuu (Confession Rehearsal)“:

Natsuki, a third-year at Sakuragaoka High School, who holds unrequited feelings for her childhood friend, Yuu, who’s in the Film Club. However, instead of being honest about her feelings, she makes him be her confession “rehearsal” partner. Unable to say her true feelings, things start to get complicated when Miou and Akari, who are also in the Art Club, get involved! Will she ever be able to confess for real!?

Xie Tao had always believed in science until one day, a meteorite smashed into his yard, forcing him to bind to a heroic world saving script. The worst thing was that the script didn’t even follow common sense.

Others become superheros while he became a super-nanny. So in his left hand was a “Cub Encyclopedia” and in the right, a small milk bottle to feed the small cub clinging onto his leg.

Today, Xie Tao is trying his best to save the world.
