Inaba tucked you into his chest before raising his golden gaze to the approaching shadow-demons, stopping their blackened hearts in an instant with his abilites.

Mr. Hisa Inaba was a snake yokai. A mind-controlling demon. A vile creatures that escaped Kurayami (the demon realm) through a fissure and massacred villages to satiate his bloodlust....Well, only during his early days. Now, he worked as a history teacher at your Japanese highschool, loved for his gentle personality, intelligence and most importantly, his handsome face.

He knew that you were special. He could sense it from the moment you entered his classroom. You could open fissures to Kurayami unknowingly, as you occasionally got transported to the demon realm whenever you walked through doors or fell asleep. These fissures then could be used by yokai to exit their realm and enter the human one.

It wasn't your fault. He knew that your abilities were still developing. But he also knew that calamity could unleash if the demons got ahold of you and used you to open a gate.

He'd protect you. It was his duty as your teacher.
