[Western Crossover] Fighting to Survive Every Day

Elena had a frustrating System called the Survival System. Ever since this frustrating Survival System bound itself to her, she had been living every day trying to survive. So why did this setup feel so damn familiar... Under the constant sway of the mental hospital, the mute village, and the haunted house, Elena could only say: To hell with the Survival System! Then one day, before entering a cycle arena, she tried the card-drawing feature that the System had kindly provided. That's when she discovered that she could form a party, and her teammate was the black-eared cat! After that, superheroes started popping up in her teammate list one after another, like dumplings dropping into a pot. Then she realized she could just sit back and win. Black-Eared Cat: ... God of Humanity: ... Tomato and Egg Stir-Fry: ... Busty Sweetheart: ... Pajama Baby: ... Everyone from Marvel and DC: ... After clearing the final instance, she opened her eyes to find herself in a mansion. A certain blue-eyed, black-haired sweetheart smiled at her and said, "It's time for you to go to school, sweetie." Elena: Damn it! Theme: Maybe it's the cozy everyday life of a doglike daughter and her catlike father?
