Ye Shu, a good-for-nothing otaku, traveled through time and space, finding himself in a mediocre modern city. With no supernatural powers, let alone superheroes, he expected to live an ordinary life. However, at the age of eleven, his life took a surprising turn. "Attention, freshmen! No student is allowed to enter the Dark Forest. This is for you, Ravenclaw Ye Shu! As a senior, you must not do anything that might lead the freshmen astray!" Dumbledore declared at the freshman welcome dinner. "A cauldron is for brewing potions, not for cooking. Ravenclaw students, especially, do not imitate your senior, Ye Shu!" Snape sternly warned the freshmen during Potions class. "Broomsticks are for riding, not for standing on them and yelling about flying. Do not imitate Ye Shu's absurd behavior!" Madam Hooch declared, broomstick in hand, addressing the freshmen. "What on earth did this senior Ye Shu do that angered everyone?" The freshmen looked at each other in bewilderment.
