AU where SJ transmigrated into blue lock when SY entered his body, and as a character who gained awareness when the system messed with him, he knows that he should make the most of this life for it to be completely different from the ending scripted for him ('he' would have lost in the first selection and never be mentioned again).
Honestly, SJ was kind of excited after transmigrating into blue lock. The system of SYs had given him the required info about his scripted future and the knowledge that a modern person would have, and the ability to speak Japanese before skedaddling to go tend to his host. Huh.
That aside, he had full confidence that he was the smartest person in the whole building, even if he had some knowledge gaps regarding the current levels of propriety in Japanese culture (There was a guy literally hanging off the back of another. That can't be normal, right? Oh my god he's sleeping now too.)
During the first selection test, he'd initially channelled his inner street child, mainly focussed on passing and striking to the best of his ability. He realised soon that with his Peak Master intellect, why would he only focus on himself when he could be manipulating the field to win, like how he used to manipulate battles (literally and figuratively) in his favour?
He'd gained the moniker of the Puppeteer, for his ability to read and manipulate the field to always come up top. After the second selection test he was ranked fourth (he couldnt rank higher bc in terms of ball manipulation etc he still wasnt really that strong). The reason why he worked so hard to rank in the top 6 is because he made a bet with Ego that if he could rank Ego would let him live in his own room. Usually Ego wouldnt have agreed, but having just seen him insult all the boys in his dorm to tears, he was intrigued enough to agree.
Did SJ miss the world of Pidw? Yeah, he definitely missed his sedentary life on the peak when he listened to the frequent arguments cropping up in a building of adolescent boys, and the fact that he himself was now back to being one of the said adolescent boys was awful, but the clean break from YQY and LBH was doing wonders for his mental health, with the added plus of escaping being turned into a human whatever that was.
He joined Bastard Munchen because he liked the attitude of logic and talent reigning king, and he def hates kaiser with the logic that a mountain cant have two kings, and he thinks that Ness would make a really good Ming Fan replacement or just a companion as a friend.
