The Sword Deity in Tokyo - Chapter 276: Familiarity

The world was hit by an abnormal narcolepsy, and there was a mass coma. Lee-joonhyuk was transferred to a dimensional battle field as he fell into an abnormal narcoleptic sleep. This is the story of him as he starts as a minion.

Kuramoto Daisuke, a freshman in High School was suddenly exposed to someone vanishing in front of him. Turns out he was admitted to a Special Class full of Isekai Heroes that were regularly summoned to Otherworlds since the start of their Middle School. He was told that he was to become their Support to prevent each of the Heroes' fate of dying in the world they were summoned into. Though mediocre, he realized that his ability has a great potential but it needs a lot of hard work on his part.

Unconvinced of being just the Support Character, he vowed to excavate his mediocre ability, all the while supporting the Heroes using it.

And maybe more.

A tree of 10,000 flowers, the world is the door.
The spells change a lot, but the hearts of the people are unchanged.
