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 has 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 perverted 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.

The boundaries of the worlds - The ability to control the border worlds, allowing the gate to open astral transitions between them, thereby moving any peace.
 * Conceptual existence - Demon Lords are concepts with a plurality of parallel worlds and stories (both real and mythical) who embody the endless possibilities that allow them to exist in all timelines in one form or another. In order to completely destroy their essence - the need to destroy or erase all the existing gaps of history, in which they exist in any form.
 * Divine resistance - according to the nature of its essence and huge levels of spiritual powers, the demon lords have a strong resistance to all forms of natural and supernatural influences.

Demon Loes is also endowed with the ability to convert their own spiritual powers into pure destructive energy.
