Belial (Wild ARMs 4) vs Alisa Reinford (Trails of Cold Steel)
This is one of the only non-Bluelike PCs that beats Belial - maybe the only one! But yeah, Cold Steel has storebought Vanish/Eject blocking. Normally this hardly matters since Belial can just kill with damage, but that doesn't help vs. Alisa's 3 lives. The first S-Craft won't kill, but having to survive 2 more 200 CP boosted Radiance Arcs? Nah.
Alyssa L’Salle (Cosmic Star Heroine) vs Tir McDohl (Suikoden)
Alyssa needs to use the status-immune weapon or auto-life weapon to not be ID'd, but that means she won't have the Style for an auto-revive. And even if she barely did, she'd be at ~0 Style or so and have no way to threaten a kill back.
EDIT: On second thought, she just uses the Heroine Bo as normal and relies on the Style turn regardless. But this still means shooting off her damage on turn 1, not her hyper turn, so I highly doubt that's enough to win with.
Middle
Cerya Phoraena (Tactics Ogre: Let Us Cling Together) vs Maya Amano (Persona 2: Eternal Punishment)
Probably Cerya?
Light
Dorothea Arnault (Fire Emblem: Three Houses) vs Gen (Child of Light)
Gen needs the all-in on Paralysis build to have a shot here, and I'm not sure that's enough, so probably Dorothea. (She's... less frail than I'd think in the DL, I'd have kneejerked .70 PCHP or less, but guess not.)
