Beam

Aki: Aki is someone serious but fearsome. He has several contracts with demons, the one he uses most is Zorro, a fox head that devours the enemy demon if summoned. He also uses the demon of the future, who warns him about future events so he can make decisions. He also uses a katana carefully because it reduces his lifespan.

Power: A strange demon, she has certain red markings on her head and instead of having a contract, she uses her blood as a weapon, cutting herself in battle to create weapons from her blood, whether knives, swords or katanas.

Denji: A very strong boy, possessing the heart of Chainsaw (Pochita), which, when a string is pulled on his chest, activates his other form to transform into a chainsaw (literally). Functional chainsaws emerge from the vertical half of his forearms, capable of cutting meat like butter, and his head transforms into a kind of chainsaw, with glowing eyes and a functional chainsaw on his forehead.

Makima: Not much is known about the extent of his power, but it is known that he has great manipulative power, getting everything he wants, even capable of manipulating a cruel and ruthless demon if he so chooses.

Beam possesses the body of a muscular young man and, as a demon-human, the snout and fin of his shark replace the upper half of his head; he has no visible eyes. He has short, spiky black hair and very sharp teeth. He exclusively wears a swimsuit.

When partially transformed into its demon form, its head becomes the enormous head of a shark with three pairs of eyes. In its complete transformation, its entire body resembles a shark but with multiple sets of long fins that it uses as legs.

Beam is very eccentric, naive, and innocent. He often follows plans no matter how crazy they are because he has so much respect for them. His devotion to superior devil hunters is such that he always tries to protect some idol, personally offering his blood to revive them, even if it ends up seriously injuring or killing them.

It is shown that he greatly enjoys fighting, as he eagerly plunged into hordes of zombies to eat them.

He is a demon hunter from Special Division 4 in Tokyo. His mission, as his name suggests, is to keep the city safe from demons trying to wipe out the population (him and other demon hunters).

As a demon man, Beam cannot make contracts and his powers are considerably weaker than those in his demonic form; however, he still has all the other general abilities of a demon.

Intangibility: Beam possesses the ability to swim through solid objects, allowing him to walk between walls and the ground with ease, although he does not appear to be able to carry others with him or bring large objects. Demonic Transformation: Beam can transform his head into a massive shark head with multiple eyes and a powerful bite. With his transformation complete, Beam's entire body transforms into his demonic form as the Shark Demon. Skills Enhanced Durability: Beam is very durable for a demon man, able to survive point-blank explosions. In addition, Beam has a strong sense of smell, as he was able to correctly recognize and identify people, differentiating between demon, hybrid, and citizen.
