This is a crossover between that time I got reincarnated As a slime and my hero academia. This fanfic will have all for one as the main villain and will follow the perspectives around Rimuru.

Just Cale adopting Deon

A new start.

Cale Henituse, an 18 year old red-haired youth who was considered trash by the people in the Roan Kingdom. Yes, Trash... That's what people think of him. However, there was something about him that no one else, including his own family, knew about. No, Cale felt that they really didn't need to know forever. But, soon very soon, he will reveal himself. FAMILYHEAD!OGCALE AU ADVENTURER!OGCALE AU MYSTERIOUS!OGCALE AU ABILITYUSER! OGCALE AU WEAPONMASTER!OGCALE AU BIRTH OF HERO X GENSHIN IMPACT TRASH OF THE COUNT'S FAMILY X GENSHIN IMPACT AU Trash of the Count's Family by Yoo Ryeo Han.

Cale Henituse survived wars, monsters, and scheming gods. So naturally, his reward is waking up in a world where the biggest threat is... not debuting a random guy as a K-pop idol. Failure? Death. Success? Peace and a ticket home. But seriously-who even is Park Moondae, and why does Cale have to babysit his singing career? Or Cale in 'Debut or Die' world

"What do you want from me, Nedzu?" "I would like you to study under me, Henituse-san." 'Hm? What?' "Of course, I would still want you to be safe from the villains targeting you, so you would need to stay here most of the time." 'This fucker.' Or, after falling unconscious, Cale wakes up in UA's infirmary, confused with a mission to somehow get home. Along the way, he unwillingly becomes a teacher assistant? Cale never signed up for this.

After graduating from junior high, class e managed to turn Koro Sensei back into a human. Now Nagisa and Karma are attending Ouran high school. What trouble with they cause?

"Reborn please don't let go of me! Please, if I have done anything wrong to you, tell me! You are the only one that I have left! Everyone else left me already! I can't lose you too!" Tsuna said as he held his hand out towards the fedora man. But Reborn only pushed Tsuna away and glared at him. "Let go useless boss. I have found a better sky than you so back off." He said with a glint of disgust can be seen in his eyes. Tsuna was shocked... more like hurt on what his tutor just said. Tears streamed down his face as he clenched his fist, until it turned pale. "I... I understand. I-If that is what you want... I'll let go of you all." The brunet said with a smile... a closed eyes smile. "I will never forget you all... don't forget that... Hayato, Takeshi, Ryohei, Chrome, Mukuro, Lambo, Kyoya and... Renarto." He added as he watched Reborn walk away... He smiled again... That was his last smile... On that day, the sky lost his own willingness to live... lost his reason to live... and on that day... the sky... has been lock on the cage of darkness and loneliness. His fate is so cruel... that even his guardians turn their backs on him... They turned to Vongola Nono's daughter who was found alive... even his father... Why must fate have to be cruel on him? Was it still not enough? Everything? Why? But will he be once again happy once he meets them?
