Rei

突然出现于众人面前的神秘眷属，游历过诸多地方而掌握了不少情报。带着一只被他称为「老爸」的鬼鸮。行事风格我行我素。在遵循自身信念的情况下，为达目的会有些不择手段。因不明原因，魔力偶尔会出现异常而带来强烈的痛苦。

简介来自 Bangumi

Appearing as if out of nowhere, this particular clan member has traveled far and wide, picking up a great deal of knowledge along the way. Regularly accompanied by a boreal owl known only as "Father", he marches to the beat of his own drum. He will use any means, good or bad, to achieve his goals, all the while maintaining his own set of beliefs and convictions. For reasons unknown, his essence has a tendency to go haywire, occasionally leaving him in a state of excruciating pain. [From the official website]
