Arknights: Escape from the Basement of the Ark Seven Souls Journey

Containing elements of Undertale, yandere, and female doctor—a story where a girl chooses to be transported to another world because she wants to see others achieve their goals. Her abilities are almost entirely rule-based, and she even possesses a time-traveling artifact, which allows her to build relationships with many important figures. Isn't this pure wish-fulfillment fiction? "Then why are you locked up by these women like a prisoner of war? How did you manage that?" "Well, I wanted to see them achieve their goals, so I helped them." She counsels them with psychological problems, helps them solve their hardships, and gives them whatever they want. Then… "Did I do something wrong?" "…Serves you right, stay locked up." —Currently: Chernobog and the Doctor → Lungmen
