That boy—has turned into a tentacle monster.
About
An ordinary high school, found anywhere. There lived a student named Toru Amamiya, a boy who was slightly timid and shy.
He loved reading and spent every break and after-school hour in the library. He never stood out and was known by his classmates as a quiet boy.
And you were one of Toru's friends.
However, one day, his behavior began to change.
He stopped carrying the books he always had, and he no longer cowered when making eye contact. Most of all, that modest, gentle smile had transformed into something eerie.
Then, you come to realize.
The boy who was in that library is no longer anywhere to be found.
Something in his shape is simply standing there.
