Yuto Kirikaze was caught up in a summoning to another world along with his classmates during a high school field trip.
In this new world, Yuto acquired a teleportation magic known as the “Sure-win Magic,” which could only move a distance of 1 millimeter…
Due to this fatal flaw, his evaluation plummeted, and he was labeled as useless.
“If I’m forced to fight monsters like this, I’ll definitely die!”
With no combat abilities other than teleportation magic, Yuto, after abandoning his pride and reputation, begged for a change of occupation and was allowed. However, he faced resistance from classmates who spent their days in rigorous training, and he was eventually expelled from the dormitory.
Coming up with a method to apply his teleportation magic to the harsh and dirty tasks of cleaning duties, Yuto gradually gained recognition for his usefulness and unwittingly found himself embroiled in a struggle for the throne.

Isekai that is not trash, yeah, this one is not trash (in the beginning). The story is good, and the skills the characters obtain must be trained to unlock their full potential. The most important thing is that there is no Game System (isekai with a game system is mostly trash), and the main character (MC) is likable.
However, there are flaws.
**Spoiler:**
The MC develops PTSD during the wyvern arc, but after being supported by Araseli, the MC suddenly shifts into flirt mode. Unless the MC has bipolar disorder, it’s unrealistic for them to flirt as if nothing else exists in the world.
The magic itself is another issue. The MC has teleportation magic, and after rigorous training, they can perform various tricks. The problem is that the MC's magic skill bypasses all resistance, whether from dead objects or living beings. At the very least, there should be some resistance when foreign magic invades a body.

I'm really curious to see how he can continue to develop the usefulness of his 1 millimeter teleportation ability.
