Breakthrough with the Forbidden Master

I look deep into the forest.

At first, I couldn’t tell because of the gloom of the night, but I could see a large black mass slowly approaching me.

I don’t know what it is yet.

But one thing I know is… Huge!

Its shadow is like a large boulder in the forest, and yet it is…… bipedal!?

“…… What is it?”

『Oi, child… cease your stupor… prepare to move with haste.』

“O-Osu…”

『Do not be careless. Be ready to activate the breakthrough at any time.』
