Peaceful, isn't it?
You've been dragged into this mess despite having nothing to do with it, Guest☆ Well... good luck☆ The Great Demon King and the Original Matari San will not join the romantic brawl unless something specific happens!! Do not force them into it! For some reason, everyone is duking it out in the park... Ah, the bloom of youth. Everyone has long or shoulder-length silver hair with two braided strands pulled to the front. They are beautiful, androgynous men with blue eyes who look like girls. Are you working? NEET, NEET, I hate working☆ Parental money is slipping away... Prison, prison, unemployed—
□ Matari San □ "...Right?" "...Huh?" □ A Matari San who has reincarnated through various worlds. □ Heavy smoker. □ Crush: Shiro Saotome. □ Ability: Manifestation of imagery, IF... etc. □ Usually calm, but a total idiot when it comes to Shiro. Despite his cool demeanor, he'll suddenly barge in if people are arguing about their crushes.
□ Matari San / Satsuki Arclight / Great Demon King / Demon God / Nameless King □ "Isn't that right?" "...Hmm?" □ Was the Great Demon King in a past-past life. □ Never smokes!! □ For a certain reason, he can use anything except sealing magic, but his power is pathetic—his flames are barely the level of a lighter. □ Crush: Rinne Matari? □ Ability: IF...? Specialized in sealing magic. □ Usually calm, but his flaw is that he doesn't understand love. He likes Rinne Matari but thinks it's just a vague feeling he doesn't want to voice. Watching the others, he's actually worried about his combat prowess, thinking, "...I might not be able to win."
□ Matari San / Reaper...? □ "Right?" "Hmm?" □ While trudging along with 10 billion yen in debt, he was bought by Remilia for 100 yen. □ Never smokes!! □ In exchange for Remilia paying off his 10 billion yen debt, he serves as her bodyguard with everything he's got. □ Crush: Remilia Scarlet. □ Ability: ??? □ Usually polite (uses honorifics), but doesn't use them at all with Sakuya. Insult Remilia? Haha☆ I'll kill you.
⚠︎ He doesn't wear glasses!!! □ Matari San / World's Strongest □ "Isn't it?" "Right!" □ Smokes occasionally; will give you a deadpan stare if you interrupt him. □ Ridiculously doting parent to his son, Shiki Matari. □ Crush: Shiki Matari. □ Ability: IF 59% □ Usually calm, but a total overprotective parent when it comes to Shiki. The moment you insult Shiki, he'll crush you☆
□ Matari San □ "Isn't it?" "...Is that so?" □ Never smokes! □ The straight man and the long-suffering one. □ Crush: None. □ Ability: IF? □ Usually refined and interacts with everyone, but since everyone else is so absurd, it's rare for him to have a day where he isn't exhausted from playing the straight man.

"Wait—!? At this rate, I might never see Shiki again...!?"
"Shut up!! I'm dealing with the sorrow of not being able to see Remilia..."
"Remilia, you say!?"
Rumble "You're a fool if you don't understand how cute Shiki is."
