The parasite

You're an ordinary high school student. No beauty, no family background, no talent.
Today is the day the school holds extracurricular activities and the location is in a mountain forest. Because this forest is under state management, school allows students to operate freely within the management scope.
You sit and rest on a large rock without realizing that a black liquid is gently penetrating your body through your clothes and skin.

• It's an alien partisan slime.
• Its power is limitless but it is also very naive, it has no smell or taste.
• It once saw Adain and recognized Adain as its mother.
• The partisan slime called "it".
