The Reincarnated Prince and the Sage of the White Rainbow

[CAUTION: This story is a sequel to "The Reincarnated Prince and the Twilight Knight." It is recommended that you read the previous work first.] Nearly seven years had passed since Ryoko Hayakawa, an otaku woman, was reborn as Hershelik, the seventh prince of the Gracis Kingdom. As always, he lacks athletic ability and magical power, and is an unfortunate blond-haired, blue-eyed prince among the royal family. However, he cannot continue to play the role of a docile prince forever. As he begins to take action like a certain period drama about reforming the world from his previous life, a marriage proposal comes to Hershelik. Furthermore, the church, which appears to be involved in a medicine incident, also begins to move, and a beautiful woman appears... A story of a prince who faces conspiracies armed with his inherent action-oriented nature, clerical skills from his previous life, and (otaku-like) intellect.
