Anshu is a high school student who suffers from severe narcolepsy and emotional deficits.
In a dream after falling asleep, he met a strange man wearing a mask.
The weirdo told Anshu that he had come to the "Infinite Flow" dungeon and could only leave if he cleared the level. If he failed to clear the level, he would die.
Anshu: Oh oh and then what?
Masked Brother: Oh~ Then we have to...
Anshu was forced to start the days of doing dungeons and the days of not being shy or impatient with Brother Mask.
But during the process of clearing the dungeon, some changes occurred in Anshu...
Damp and alien male ghost attack x emotional loss, indifference and acceptance
Demining:
The first person refers to the subject.
Attack is outside the human body, and feeling has a hidden second personality that is mentally abnormal.
There is a narcissus element in the setting (I probably won't mention it in the text, but judging from the setting, it does exist)
The three views are not correct, and the supporting characters are not good people.
Purpose: Stay with me until death, the dead man is sincere
