Lu Yu: “???”

Welcome to the Classroom of Meritocracy + Dropping Out. Everyone else comes to study, but Bai Lan came to drop out. Bai Lan had just returned from a wilderness survival trip in the Amazon rainforest when he received an invitation to take the entrance exam for a highly advanced high school. Persuaded by his parents, he reluctantly participated, treating the written and oral exams like a game. He thought he was guaranteed to fail. But he was surprisingly accepted. He initially planned to drop out immediately. Then, the system awakened, presenting him with the ultimate mission: as long as he didn't voluntarily drop out, and not because of his academic performance, he would gain [Invincible Luck] and [Extraordinary Physique]. The rewards were tempting, and Bai Lan wanted to try. He figured even if two ways to drop out were blocked, there was still a way. Then he discovered that this school actually had a "dropout exam." He was in luck! The result... He suddenly confronted the hidden boss, who then became his apprentice; he beat up the student council president, only to be thanked by him; he bullied a delinquent girl, who said she wanted to date him; he tried to blackmail the school's idol with his past, sparking public outrage, only to find out the idol said he had helped him resolve his inner conflicts; he self-destructed during his exam for dropping out, and a group of people rallied to his defense. Why is dropping out so difficult?!

After being transported to another world, Mizusaki Yuuma looked at the newly released "Love Metronome" and realized it was a sweet slice-of-life romance anime. However, he encountered a girl collecting Clow Cards, a pile of scrap metal collecting the Peace Star, and a Sherlock Holmes from the Heisei era. He also occasionally heard urban legends about Tomie. Fortunately, his Yorozuya (Odd Jobs Shop) always attracted strange customers who traded things from other worlds with him. There was the Battlefield Rose from the ninja world, a rebellious girl from the world of navigation, a fox spirit from Valoran, and a girl visited by eight million warriors. Kasumigaoka Utaha: Hey, you have to take responsibility! Kinomoto Sakura: My brother is so nice, he helps me collect Clow Cards. Irelia: Grandma always says... Mizusaki Yuuma: Stop nagging Grandma, when are you going to pay back what you owe? In the corner, Mai Shiranui, remembering she still owed money, was trembling. ...

Lin Jin, who transmigrated into the world of Detective Conan, discovered something amiss with his dreams. In one dream, he unleashed a barrage of attacks on Ran, but the next day, she lost her match due to a muscle strain. He dreamt that Eri Kisaki was investigating a case of female assault, and he offered to help, cooperating in reenacting the case, which gave Eri a breakthrough the next day. He dreamt that he trained with Sun Wukong, and the next day he had eight-pack abs. "It's a pity dreams are random, otherwise…" Lin Jin felt quite regretful. If he could, this thing would be far more useful than time stop.
