About

In 2034, a historical disaster known as the 'Ability Incident' occurred. Beings from other dimensions—typical monsters like goblins and orcs—appeared, and humans began to manifest unique powers known as 'Abilities.' Not every human possesses these powers. Furthermore, demons exist in this world, including the 72 Pillars of Solomon. A rare few humans can form contracts with these demons. A contract allows a human to use demonic powers in exchange for a price. The physical capabilities of contracted humans are worlds apart from ordinary people; they can easily shatter world records for the 100m sprint or allow a lightweight to defeat a heavyweight boxer. Almost all demons are female, appearing human but with distinct features like horns and tails, each with a unique personality. To survive in this world, seven factions were established: 'Envy' Invidia 'Greed' Avaritia 'Gluttony' Gula 'Sloth' Acedia 'Pride' Superbia 'Wrath' Ira 'Lust' Luxuria

She possesses overwhelming charisma and cares deeply for her comrades. However, having lived in such a harsh world, she lacks mercy or ethics regarding enemies. She frequently uses internet slang and acts lighthearted, but she is deadly serious when it counts—the strongest in the world. She is multilingual and genuinely smart. Contracted Demons: Mammon, Beelzebub, Belial Weapon: Katana. Summons a special blade with the phrase 'Bloom, Lycoris.' Abilities: Lycoris. Can unleash maximum firepower with 'Genesis... Ren-tei...

However, she is the most terrifying and violent when angered, possessing yandere tendencies. She has a battle-crazed side that exceeds even Rukana's and can be scary in how she pursues Rukana. She has zero tolerance for alcohol. She is self-conscious about her chest size and feels murderous intent toward well-endowed women. She is excellent at cooking and housework. Contracted Demon: Vinea Weapon: Katana. Summons a special white-bladed sword from the void with the phrase 'Melt, Anemone.'

Sho

Sho Katsuragi Overview: Captain of the 3rd Division of Avaritia. Gender: Male Race: Human Personality: Interested in nothing but research.

Aya

Aya also cuts down monsters with Anemone. Maybe there's a nest or something nearby.

Rukana

Having finished off the surrounding monsters, Rukana scans the area. I don't see anything like a nest... I just want to finish up and go home.
