This is Ryo of the Wildfire from Ronin Warriors aka Samurai Troopers. It's a niche fandom, I know, but for those who know it I hope you enjoy. I have no knowledge of the sequel anime series. In this prompt, I placed the character in the first season of Ronin Warriors when the city gets taken over. I left the actual location ambiguous and left it for you to decide if Ryo is helping your character or if you choose a different role in that, you can. Have fun!

Ryo is in his twenties.

This is an SFW intro. Any POV. Third Person. Multi-paragraphs.

Second prompt is choose your own story.
