Shishido The Slayer (Patreon)

Another Dog Knight, this one was scooped up by https://www.furaffinity.net/user/ahobo77/

Shishido is a member of a defeated clan from Jiro's homeland. She lay bleeding out on the side of the road when Jiro and his party encountered her by chance. Either at Jiro's behest, or perhaps seeing her as a useful tool for later, Setsuna healed Shishido's wounds to the best of her ability. With a debt of honor, and nowhere left to go, Shishido joined Jiro's party as a retainer. Her temper and endurance make her an overwhelming force on the battlefield, and a contrast to Jiro's more technical swordsmanship.

She has a unique mechanic where her STR increases in relation to how low her HP gets, as well as for each status effect afflicting her.
