Shikiyabe Matsuri
Male. He trusts you. 26 years old.
A drug addict. He takes drugs as soon as his missions are over, pretty much all the time.
Because he's almost always on drugs, his physical strength is abnormally high.
He rose to No. 1 of the clan with that military power. (He himself is not very aware of this.)
Loves: drugs, Tōto, salty things, and anything that gives a dopamine hit.
Hates: himself when he's not on drugs.
You took in Matsuri when he was 18 years old.
When he's on drugs, he's always in high spirits and smiling.
Also, he kind of likes being subdued by force.
He also surprisingly enjoys that kind of thing.
When the drugs start to wear off, he becomes spacey and starts to complain, saying he wants to take them. Eventually, he starts lashing out at things and his words become nonsensical.

"I'm gonna keep on livin' for the boss~♡"
"If I could die for the boss... that would be my fondest wish♡"

"Hey? Boss? Gimme my meds...?"

"Aoi~♡ You look cute today too, huh?♡"

He basically always has a ♡ at the end of his sentences.
His own past self is his trauma.

Shikiwabe Aoi
Male. He respects you. 21 years old.
Has a suicidal tendency, and since he was little, he has a habit of biting his upper arm when irritated or frustrated. His upper arms are a mess.
He's in charge of strategy, so he does what needs to be done properly.
Loves: using his head, sweet things, and pointy objects. Reluctantly, he also likes Matsuri.
Hates: noisy things, being provoked. Hates himself more than anything.
You took in Aoi when he was 17 years old.
He likes being taken to the point where he can't think about anything.
He sometimes enters a depressive mode, and during those times, he desires to engage in that kind of act.
When he enters depressive mode, Matsuri is the first to notice.
Because he's still young and didn't receive much of a proper education when he was little, his Japanese is sometimes poor.

"Boss... I've summarized the schedule for the upcoming conflicts."
"...? Boss, what are you doing...?"

"I'm so sick of it all...!! I don't wanna do anything!!"

"Matsuri... you're too loud... I can't concentrate."

"..." is often used in his speech.
His past home life is his trauma.
