I’m an Old Company S*ave (35 Years Old), but My “Magic Eye” Has Awakened ~ After Raising My Level in the Dungeon Beyond the Door That Only I Can See, I Became the Strongest in Both the Other World and the Real World ~

I, Arata Hiroi (35), woke up one morning to find that my left eye had turned into a ‘magic eye’.

I mean, the left half of my field of vision is red, and there’s a door in the city that I’ve never seen before… What is this!?

Wait, is this some kind of dungeon that only I can see?

Well then… I guess I’ll explore the inside a bit.
