In an Anime Crossover, the Heroines Are So Irresistible!

Banxia transmigrates into a crossover world and discovers that it includes the world of Jujutsu Kaisen. Just when he thinks he's doomed, he gets a golden finger: the Treasure Chest System. By changing the world's original course, he can earn mysterious treasure chests. He can also obtain keys from the heroines. From the start, he gets a purple treasure chest. [Congratulations, Host! Your reward is Full-Power Form (Cursed Technique).] [Full-Power Form: The body's cursed energy receives an explosive, all-around boost. Every cursed-energy-infused attack ignores defense and deals true damage. Lasts 251 seconds.] “Holy crap, that's overpowered!” With Full-Power Form, Banxia becomes an overpowered monster in Jujutsu Kaisen. To get more treasure chests, he has no choice but to change the original tragedies across the crossover worlds. But treasure chests alone aren't enough. He needs keys, too. With no other option, Banxia turns to the beautiful girls he's saved and gives them a “kind and friendly” smile. At the entrance “Don't turn around, little sis. It's your big brother.” In the Service Club “Yukino, you smell so good.” In Kōshu “Mitsuha, you don't want to disappoint your grandma, do you?” Once he has amassed enough power, Banxia quietly raises his eyes and gazes at the colossal being high above in the sky. They say that upon that divine throne sits the strongest god, a war god hailed as the King of Kings and God of Gods. “To you who stands alone at the pinnacle of power, let me set you free.” “An interesting monkey.” “...” [Ding! Congratulations, Host! You have defeated the “War God.” Reward: ...] The companions are mine, the Star Cup is mine, and the heroines are mine, too!
