[Western Crossover] Mercenary? Superhero?

Mogu is a mercenary. Really.

He was born in a peaceful country, in a peaceful era, part of a peaceful new generation. Really.

He's trapped in a useless city with nothing but monsters for company. The only way out is to clear its stages. Once his survival time runs out, or he suffers a fatal blow, he'll return to the city, and the wait before the stages refresh will grow longer. Really.

He met a superhero. Really.

He fell in love with that superhero. Really? Or not?

Theme: Redemption and being redeemed. Who saved whom?
