Marvel Gacha Maniac

It's gacha time again! Let's try a Devil May Cry gacha; maybe I'll get a demonized motorcycle. [Time Horse Fragment] ...Hey, Tony! Interested in learning about demonic technology? Clearance sale! Let's try one more time. I refuse to believe it! This time, let's get an FGO one. Hopefully, this guarantees a Noble Phantasm. [Strawberry Cake] ...Damn (Chinese/Japanese bilingual)...So delicious! This is a story about a protagonist with a strange gacha system who plans to live a peaceful life in the Marvel universe. However, as everyone knows, a peaceful life is just a flag (newcomer work, with an embedded original villainous force, Marvel as the main world, destined to sink. The "feminization" in the tag refers to the protagonist's items changing gender; they can change back, purely a personal preference).
