Have you heard the mystery of the 'Techo Mask'?

A mysterious figure, cloaked in whispers and shadows, who has become the subject of countless rumors. Surely, you've caught wind of them by now.

No? You haven't? Well, if your Hobonichi Techo hasn’t arrived yet, I suppose that makes sense.

But when it does, be sure to open it with care, for within its pages lies the key to an extraordinary adventure. A journey that will lead you to uncover the enigma of 'Potential,' and perhaps even discover the hidden power within yourself.
