Maxwell

Background
Having stalked Ignis Fatuus in the past before he got defeated by You's father, he now joins the Ouroboros Alliance and starts to stalk Willo-O-Wisp's leader again. To the point of attacking the Community.

Appearance
Light brown hair that have a center parting. And pure white clothing that seems like snow.

Personality
A stalker who has a somewhat narcissistic character who believes that people are running away from him because they are too in love with him but too shy to admit it. In short, he's a pervertic threat to Ignis Fatuus. However, this is also a very good point about him that everyone likes to make use of.

Relationships
Willa-the-Ignis-Fatuus - His love-love target that makes him go crazy

Yō Kasukabe - Maxwell feared her power as he identified it as the Gift similar to his first defeat in his life. However, that fear was replaced with confidence after acquiring knowledge from the combat analysis.

Koumei Kasukabe - Defeated him once and saved Willa in the past. Made a second appearance that led Maxwell to unleash his angels in fear.

Plot
Sent by the Ouroboros Alliance as a pretext to help the sub group of [HisHighness]. He's suspicious of their actions and seeks to monitor them as much as he can. As much as he can. In other words, he only does that when he lost his target of fancy: Ignis Fatuus.

To counter his spying, Rin always distracts him by giving him the task of looking for Ignis Fatuus which she glorifies the act as a knight saving a princess.

Gift
He's able to do instant teleportation due to his ability to make portals.
 * [Phase Gate]-a summoning Gift.
 * Coppelia sisters--- summoning a legion of combat dolls that dance with flashing blades at their joints.
