Jin is... a leetle obsessed with Ragna. "Ah~! Long time no see...BROTHER!!!~"
- The creators aren't even trying to hide it. In Teach Me Ms. Litchi he has hearts over his head and in his eyes every time Ragna speaks.
- Jin's obsession is played with a lot in the various gag reel endings in the story modes - even in those for mostly unrelated characters. From Relius Clover's BBCS Extend gag reel, where he mind-swaps several of the other characters, in particular Ragna and Jin:
Ragna(?): Is... is this... Brother 's body...?! *Pant* *Pant* Oh, Brother... BROTHER!
Jin(?): NOOOOO! Hand-check, Jin! Hand-check this instant, you freaky—!
Ragna(?): Finally, I'm where I've always wanted to be... inside Brother's body...! *Sniff* *Sniff* It 's like a dream come true...!
Jin(?): This isn't real...! Nope! I'm dreaming, and I'm gonna wake up, yeah?! Somebody pinch me—dammit, Jin, not YOU!
- In Jin's joke ending of CS, he's trapped on an island with 3 fake Ragna clones. The first thing he does is tell Noel to leave, and that he's going to have fun....
- In Chronophantasma, he ends up back on the island. He insists that his feelings for Ragna are entirely murderous in nature, but the Ragna clone doesn't buy it. The clone even admits to being slightly curious towards Jin as well. Then again, he was created from Jin's imagination.
- In episode 2 of Teach Me Ms. Litchi Again of CP, Jin constantly pesters Ragna for a "body examination". He also agrees to teach Tao in exchange for a method in catching Ragna. The last we see of the two is Jin dragging tied up Ragna off to do god knows what with him.
