Enzukai

Enzukai is known to manipulate Isamu's emotions into believing it was his fault that Senzai died, taunting him that Enzukai is the only one who was there for Senzai, blaming Isamu for his sins in the raft part of Book 2 Chapter 3. Based on what is seen, Enzukai is sadistic and manipulative, creating an entire cult which saw it as their god who deeply care for it, despite seemingly not showing any genuine, real care for its worshippers.

ABILITIES:
Transformation: As confirmed by a lore writer, Enzukai can transform into three different forms at most.
Water-Breathing: This is presumably an ability that Enzukai is shown to have. Enzukai is able to stay alive in its seal for hundreds of years under the ocean without drowning.

Mimicry: This ability is a main ability of all the Four Beasts, including Enzukai. It is able to mimic any parts of this reality it wishes and recreate it in its pocket dimension.
Immortality: As confirmed by lore writers, The Four Beasts were created 3000+ years ago. It seems it is immortal or has an impossibly long aging process.

Telekinesis: At the end of Jealousy Chapter II, Enzukai pulls Isamu Uchiumi from a distance towards itself.
Super-Strength: After Enzukai pulls Isamu towards itself using telekinesis, it rips his heart out with ease and crushes it.

Levitation: This is possibly an ability Enzukai is shown to have. When Senzai introduces Isamu to Enzukai, it came out of the water floating, though it might be applied that its telekinesis ability could have a play in this as well.

APPEARANCE:
has crimson red skin, green-yellow eyes, long chartreuse yellow horns, yellow-ish sharp teeth, and it has a third greenish-yellow eye on its forehead. It is wearing a tattered and partially ripped long skirt. It wears a black beady necklace around its neck and seems to not wear any top. It has a build of broad shoulders with a small stomach. It is also more angular than before.
