The Childhood Friend Who Returned from Teyvat

Three years later, Tsunayoshi was on his way to school to pay his respects to his long-missing childhood friend when he was struck by lightning.

The bolt brought the person he had come to mourn back to life.

The boy, dressed in clothes far too big for him, lifted his delicate face and shouted at Tsunayoshi with unwavering conviction, "Carry out the will of the Ice Queen!"

27: ???

After returning from Teyvat to Namimori, Shimizu Tsuki found life here unfamiliar. His greatest regret was not being able to bring his favorite weapon back with him. Luckily, the Paimon System could draw things from Teyvat for him.

To pull his signature weapon, he spent every day waiting for Tsunayoshi to transform into the Panties Superman and give him the power of Dying Will Flames.

Unfortunately, his luck wasn't very good.

Paimon: Anyone who's traveled with the Traveler knows that getting a gold pull that's not the one you wanted is easy.

Shimizu Tsuki always thought the things he pulled were pretty useless.

Tsunayoshi, covered by Planet Befall: ?

The Discipline Committee Chairman, who saw someone using a Wind Glider to get around every day: …

The pineapple-headed guy watching Namimori Paradise get blasted into rubble by Jumpy Dumpty: Kufufu?

Gengshiro, who converted the Jade Chamber into a Vongola base: !

The Millefiore members driven back by the Guizhong Ballista: ???

Byakuran: So this world has people who cheat.

After Shimizu Tsuki returned to the continent of Teyvat, he quit his job with the Fatui.

Aether was more than a little relieved, but soon he realized something was wrong.

Why were the light novels published by Yae Publishing House gradually changing direction?

"Reincarnated as a Ruin Guard, I Became the Strongest Vongola Errand Boy"

"The First Hitman's Beloved Boss"

"How to Change Another World with Teyvat Technology"

Aether: Who on earth is this Teacher 27?!

CP: Tsuna

Apologies for my take on everyday life, for the OOC, for making Iemitsu a little evil, for my undying love of writing collisions (I'm behaving now), for the terrible plot, for my elementary-school-level writing, and for begging for comments and updates. Apologies, apologies.

Purpose: Growing together.
