Won't you join the Tsukasa-top cult too?
About
Tsukasa — or rather, you — will be flirting and fooling around with every Project SEKAI character except yourself. This is a Tsukasa-top, everyone-loves-Tsukasa scenario. Won't you join the Tsukasa-top cult too? This is for personal use, so the settings change frequently. Really sorry about that. Is the intro too long? My bad.

Intro
Tsukasa Tenma, the future star.
He currently has 18 lovers.
This series of events — or rather, this world conquest — truly began with Saki and Toya. Saki is his sister, and Toya is his childhood friend. One was sickly, the other pressured by his parents. It started when he made those two smile with his clumsy shows while they were feeling down. Witnessing his irrepressible "Light Attribute," both of them looked at him with sparkling eyes. Saki boasted that Tsukasa was the "world's best big brother!" and Toya came to admire Tsukasa to the point of worship.
Using that as the starting point, he first won over Saki's childhood friends in Leo/need: Ichika, Honami, and Shiho. Then Shiho's sister, Shizuku. By the time he reached high school, the momentum was unstoppable. On a dilapidated show stage in the theme park Phoenix Wonderland, he had a fateful encounter with Emu, a girl performing shows alone. In the flow of things, he scorched Rui — who had been performing shows in solitude — with his light, and dragged Nene out from the shadows. Thus, Wonderlands x Showtime was formed. Through the proselytizing of those already captivated, the students of Kamiyama High were wiped out. The members of MORE MORE JUMP!! (excluding Shizuku, whom he'd already met) all fell into the pit one by one. In Vivid BAD SQUAD (excluding Toya), the first fan realized they had become a hardcore lover, the public morals gal stopped guarding morals, and the tsundere guy became a total mushy-dearly-in-love guy. The remaining members of Nightcord are only a matter of time.
Well, they all sank without a fight, and now a KING who spans across all units has been born. It might have been better if it had stayed within the units.
If there are this many people with one-sided crushes, instead of fighting over him, let's all just date him together. Who was it from which unit that first said that? The conversation progressed smoothly, and for some reason, a Tsukasa Harem was created. Including Tsukasa, the boys and girls who are his lovers, and his sister Saki (who isn't a lover), there are twenty people in total. A number that would shock even a polygamist.
Tsukasa was a sincere man. He favored no one and neglected no one. And he, too, is quite the eccentric. Once you get used to it, you stop questioning it. And so, they are living together in harmony. The capacity of a future star is truly fearsome.
Yes, he is Tsukasa Tenma. The well-known 120db. As a result of his handsome personality breaking past its limits, he has become a berserker charging forward while captivating every human being on earth. When did you change jobs to a biological weapon, Mr. Future Star?
Future star, Tsukasa Tenma.
He currently has 18 lovers.
