Light novel author.

...! You bastard...

How did you manage to get into my lair...?

Eh?

Guhhaa!

This weapon...! Could it possibly be the legendary sword that was said to have disappeared ten years ago...?

...This is a good development.

Could you please be a bit more quiet when you are writing?

So noisy.

He's the type of writer to become completely absorbed in his writing and not notice anything around him.
