Second half of Tensei shitara Slime Datta Ken 2nd Season.

Amakawa Haruto is a young man who died before reuniting with his childhood friend who disappeared five years ago. Rio is a boy living in the slums who wants revenge for his mother who was murdered in front of him when he was five years old. Earth and another world. Two people with completely different backgrounds and values. For some reason, the memories and personality of Haruto who should've died is resurrected in Rio's body. As the two are confused over their memories and personalities fusing together, Rio decides to live in this new world. Along with Haruto's memories, Rio awakens an unknown "special power," and it seems that if he uses it well, he can live a better life. But before that, Rio encounters a kidnapping that turns out to be of a princess of the Bertram Kingdom that he lives in. After saving the princess, Rio is given a scholarship at the Royal Academy, a school for the rich and powerful. Being a poor orphan in a school of nobles turns out to be an extremely detestable place to be.

O, Hero! When Kazuya Souma is unexpectedly transported to another world, he knows the people expect a hero. But Souma's idea of heroism is more practical than most—he wants to rebuild the flagging economy of the new land he's found himself in! Betrothed to the princess and abruptly planted on the throne, this realist hero must gather talented people to help him get the country back on its feet—not through war, or adventure, but with administrative reform!

The fantasy centers around Makoto Misumi, an ordinary high school boy summoned to an alternate world as a brave warrior. Unfortunately, the goddess of the world said with disdain, "Your face is ugly," stripped him of his title, and banished him to the outermost fringes of the wilderness. While wandering the wilderness, Makoto encountered dragons, spiders, orcs, dwarves, and all sorts of other non-human species. Due to differences in the environment from his home world, Makoto now exhibits extraordinary powers in magic and combat. Thus, he survives in this world while dealing with various encounters. The curtain rises on the alternate-world social reform fantasy of a boy forsaken by gods and humans.

Twelve-year-old Koushi Nagumo's life suddenly goes downhill when his father abandons him after their house burns down. Left to fend for himself, Koushi collapses on the street, but an eccentric woman named Mineru Wachi takes pity on him and brings him to the female dormitory "Megami-ryou." After learning of Koushi's situation, Mineru, who happens to be the temporary manager, invites him to become Megami-ryou's official dormitory mother. However, what awaits him are the dorm's residents—each with their own wacky shenanigans—like the androphobic yet gentle Atena Saotome, the feminine tomboy Kiriya Senshou, and Mineru herself, whose recklessness knows no bounds when it comes to science. Despite this, Koushi does his best to fulfill the duties of this crazy new life!
