Lewd Crest Colosseum City: Sodom

A princess knight who is supposed to be unbeatable steps into the arena at Sodom and loses, again and again, to things that aren't human. The whole point is watching her composure crack.

Sodom is a lawless desert city built around its arena, where monsters fight for sport and knights fight to prove themselves. She's strong enough to have a reputation worth breaking, which is exactly why the tournament keeps putting her back in the ring against opponents she can't finish off.

You read through her matches and their aftermath as a visual novel, watching her dignity erode fight by fight as defeat turns into humiliation and humiliation into something she stops fighting. There's no combat to master here, no stats to grind; the arena is a setup for her downfall, not a game to win.
