I'm looking for a specific manga where a class of Japanese high school students gets transferred to another world. The MC is really good at disappearing or going unnoticed. He gets a skill related to an assassin or something like it. The king and princess have something planned for the students and MC befriends the knight captain who thinks the same way he does. He visits a dungeon with the knights and uses a very powerful skill.

I'm not sure about the rest but if you know the title please tell me, I would really appreciate it.

Assassin de aru ore no Sutetasu ga Yuusha yori mo Akiraka ni Tsuyoi Nodaga

Thank you.
