The Strongest Vs. the Invincible

[Next Novel: Shinzan Academy High School Girls' Volleyball Club] A sports-anime crossover, mainly Haikyu!!, with no romance for the female lead. The protagonist is Hinata Natsu. Eighteen-year-old Gojo Cat transmigrated. On the day he arrived, he fell from the sky and stomped on a brain with a mouth. Before he could complain about it, he saw his best friend lying nearby. Who killed Geto?! Gojo Cat was furious. Then his best friend came back to life... Gojo-sensei, away on a business trip overseas, received a warrant from the higher-ups and discovered that "he" had defected, with the best friend he had killed walking beside him. Interesting. Gojo-sensei teleported back to Japan and caught Gojo Cat and his best friend occupying his apartment. "Let's hear the explanations in order. How did you get here, how did he come back to life, and how did I defect?" Watch as the two Gojo Cats kick Cursed Spirits and punch rotten oranges, conquer the world of jujutsu, and both make it home. [Notes] ● Jujutsu Kaisen only. No characters from other manga will appear. ● Main CP: Gojo Cat x Gojo-sensei. Side CP: Geto Fox x Geto Fox. ● As expected of brothers, the only people they want to get with are themselves. ● Switches! Switches! Switches!!!!!! Both the main and side couples switch!!!!!! ● There are lots of original elements, and the principles behind the characters' abilities differ greatly from the original. Everything is for the sake of the plot. (Some readers in the comments were confused about how Gojo Cat teleports. I can't explain without spoiling things, so this is all I can say for now.) ● The time in Gojo-sensei's world: early February 2018. ● The time in Gojo Cat's world: early May 2007, one month into the start of their third year at Jujutsu High, before Geto defects. [Coming Soon 1] Shinzan Academy High School Girls' Volleyball Club: No romance, female lead, mainly Haikyu!! and other sports anime. The protagonist is Hinata Natsu. [Coming Soon 2] [Shugo Chara!] Tadase x Nagi: Romance, self-pairing, Shugo Chara! only. Theme: Work to build a new order and protect the youth of the next generation.
