I Must Survive in This Family

Nan Dong lives in a family of four. His only wish is that his mother will die soon. At home here, my father used to be a member of the Holy Court, a magical girl organization on the side of justice. His strength was SS level, but for some reason he was paralyzed in bed and his strength was only E level. My younger sister is Comet, an S-class magical girl criminal. And his mother, Tong Xinlu, is a former SSS-level demon leader and the initiator of many human mass extinction events. For some reason, she started playing family games on a whim. The above-mentioned people are all family members of the dolls captured by Tong Xinlu. As the only ordinary person in this family, how long Nan Dong can survive depends entirely on how long it takes for his childlike innocence to tire of this family game. .... .... [This target has started Side Mission 1: Acting.

[Task requirement: Successfully kill Tong Xinlu before she is no longer interested in you...] Nan Dong, as an ordinary person: "?" Even if you can get rewards after completing system tasks, what's the use? Shall I fight the demon leader?
