It's back! Life is back to normal for Saiki, Killua, Ban and Gowther. Or so they thought. Another problem has reared its ugly head. This time, in Saiki's world. Since Saiki returned to his world, he's noticed something slightly off. He ignored it because he had just been isekai'd, nothing was normal. But, when the rise of a rather destructive group threatens to destroy his perfectly average life, Saiki decides to take action. Is there anything he can do? Not by himself there isn't. Yet again, the four of them are called to action, but this time, to save Saiki's world. Sequel to This is Why I Don't Touch Weird Space Rocks. You should probably read that first. I own nothing. Nada. Not the pictures, not the characters... well I do own the villains, but other than that, N O T H I N G.

When Saiki, Killua, Gowther and Ban find themselves in the world of Quirks they work together to find a way back. Includes: some spicy revenge, spicy character development and an even spicier sequel! I do not own any of the characters in any of these stories but the plot itself is mostly mine. Any art I use isn't mine unless I say otherwise.

Out of nowhere, Saiki is transported into a new world full of unique people. In this world, heroes exist, and they fight to protect the people from villains. He was brought here by those very villains that go against the heroes of this world. He decides he'll play with the villains a bit and becomes a spy, later transferring to UA and becoming a class 1-A student. (This was originally a Saiki x Deku fanfic, but I changed it to a Kirishima x Saiki as I thought they were cuter together. Because of this, Deku will be close to Saiki, but they are JUST FRIENDS. The true romance is now a slow burn.)

Ouran High School is a well-known school in Japan, a school for the rich, the powerful and the intelligent. Though one fateful day Ouran's principal and administration agree to open up a new program-a baking program-with this new fact gives an instant spark upon Saiki's sweet tooth. As he works his way up into Ouran Private Academy for the success of getting into the school's newly added program, Saiki (being a commoner and all) also catches a spark with the Host Club, and it doesn't take a psychic to know things will fall into a disastrous circle of clichés from there. (I am a manga reader and Anime watcher for both animes, details from both the show and manga will show up in this book!)
