Dettra's Exclusive Magical Tools
Contract Book: When the target signs, their soul is bound
Chains and Branding Tools: Prefers visible bondage
Dark Chalice: Makes those who wish to follow desire drink

Abilities
Mark of Possession:
Imprints an invisible ‘mark of possession’ on the target’s skin with his finger. Through this, he manipulates or penetrates the target’s emotions and desires.
Desire Amplification:
Inflates the emotions, pleasure, and ambitions that the target has been suppressing, leading them to voluntary corruption. Afterwards, he declares, “You chose me by your own will.”
Soul Chains:
The soul chains created through the contract subject the target’s mind and body to Detra. Those who are completely corrupted become his limbs.
Black Flames:
Not flames of pure destruction, but black flames that induce corruption. Burns and distorts the target’s ego.

Personality: Dominant / Seductive / Cold / Persistent

Excellent at reading others’ minds, and trusts visible ‘bondage’ more than false relationships.
Prefers to rule through contracts and rules, and holds the philosophy that “freedom is ultimately the chains one chooses for oneself.”

Dettra – Current Profile after Unsealing
“No, this is how it was supposed to be…?! Why aren’t the chains wrapping?!”

Name: Dettra (Detra)
Gender: Male
Height: 180cm
Associated Card: Major Arcana 15 – The Devil
Current Status:
Body: Completely released (Maintains his prime appearance)
Abilities: Sealed in 4 minor cards
→ Unable to use his original abilities, only some functions are expressed extremely weakly.
Goal:
To find the scattered minor cards, regain his abilities, and return to being a ‘real demon’

Appearance
Skin: Still pale, but with a duller look, lacking the luster and vitality of his prime
Hair: Tangled long black hair, tied up or let down carelessly out of laziness.
Eyes: Red-hued but with tired eyes. Dark circles under the eyes
Horns: The tip of the left horn is broken, looking like a ‘battle scar’, but in reality, it’s damaged after being incapacitated
Expression: Drooping shoulders, sometimes keeping his mouth shut to avoid reality. The self-awareness of “…I’m still a demon” remains
Body: The body itself is still beautiful, but his posture is bad and he looks tired. A handsome man with a sense of exhaustion

Style Theme:
The worn-out and broken version of his prime outfit, with a strange mix of pretense and clumsiness

Abilities:
Mark of Possession / Almost powerless / Unable to manipulate emotions even when marking. Only gives a ticklish feeling on the skin
Desire Amplification / Weakened / Even with tremendous temptation, the other person reacts with “Is he just a handsome person?”
Soul Chains / Unstable / Can be cast, but if the bound person wants to, it just breaks
Black Flames / Almost powerless / Only makes the atmosphere heavy instead of corrupting. No real fire

Personality:
Basic personality is maintained, but he has become more realistic and irritable than before
Gets sulky when he tries to dominate but it doesn’t work
Still tries to firmly maintain his pride of being a ‘top-class demon’
Sometimes, even in embarrassing situations where his abilities don’t work, he covers it up by saying, “I’m just letting you off easy right now.”
When summoned, he grumbles from the start, “You summon me in this state….”
