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 and Abilities
Demon Lord (Mao) - the deity endowed with a special privileged status and a huge amount of spiritual energy. Mao is conceptually impossible to win without having the power to destroy stars. 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.
 * Astral manipulation - the ability to allow demon lords to work on the spiritual and astral level, which allows them to do damage to another Mao, which are immune to ordinary physical attacks ignore the intangibility and enjoy the spiritual senses. Mao is also endowed with the ability to convert their own spiritual powers into pure destructive energy.
 * Host Master - Demon Lord's right to form and to impose other beings created by himself, Games, that is to convert their spiritual and astral forces in the form of such tests, to stake your own soul and your whole existence, thereby forcing the laws of the world and reality to obey the conditions of the Games.
 * Maxwell's demon - demon paradox is the concept of thermodynamics and manipulating boundaries.
 * [Phase Gate]-a summoning Gift.
 * Instant Teleportation - Maxwell has no limitations in the form or place obstacles in its path, there is no movement, gestures or spell. It is directly linked to the space-time manipulation and is a dimensional transition through time travel flows of other dimensions, and then return back to their abandoned timeline where Maxwell appears at an arbitrary point in space. This movement is not possible to observe the usual feelings and perceptions.
 * The boundaries of the heat - the ability to control the thermal boundary compressing and extracting heat from anything, thus creating fire storms and freezing blizzard. Can handle heat in an amount equal to infinity.
 * Necrosis - extracting heat from the body of opponents to the state killing cells of the body.
 * Molecular spiritual regeneration - the ability to instantly repair damage, the reconstruction of the destroyed body at the molecular level. Rate limits of such regeneration is extremely difficult, due to the fact that, most likely, it can be regenerated even if his body is completely destroyed and erased, or even if it will be affected by the spiritual.
 * Calls - in connection with their weakness in close combat and fragile body, Maxwell often used to combat the appeals of different creatures from other worlds and opportunities.
 * Coppelia sisters--- summoning a legion of combat dolls that dance with flashing blades at their joints.
 * Nano-angel - call powerful war machine that has the appearance of an angel with one wing, the equipped armor, sword and spear. Maxwell strong appeal, but its potential remains unknown.
