- Alliterative Name: Mei Meiyo.

- Dual Wielding: Often uses both her wakizashi and katana in combat.
- Expressive Hair: When flustered, Mei's ahoge pops right up causing her further embarrassment.
- Family Business: The Meiyo family has served as swordfighters for countless generations. Too bad they're all dead now.
- Good Colors, Evil Colors: Sort of. Her wakizashi is white and is most often used. Woe come to those who see her draw her black katana.
- Idiot Hair: Mei has a hidden ahoge that she tries to keep brushed down. It doesn't always work though.
- Just Following Orders: Has killed people as 'Hit Requests' because she feels she cannot deny them.
- Master Swordsman: As her talent is Kenjutsu Master. Kenjutsu being the art of swords.
- No Social Skills: Due to her lack of common knowledge, she often can't follow a conversation and it ends with a sword pointed at the other's throat.

- Technicolor Eyes: She has naturally red eyes.
- The Stoic: Mei Meiyo never smiles.
- Why Did It Have to Be Snakes?: With bats. It's a fear which has extended from her childhood to the present.

Keroko, SHSL Herpetologist
- Animal Motifs: Gee, I wonder...
- Animal Themed Super Being: She's traded her humanity for frog powers.

- Expy: One could argue that she's an Expy to Tsuyu from My Hero Academia.
- In a Single Bound: She can jump really far thanks to being part frog.
- Little Bit Beastly: She has frog like appearance traits such as webbed fingers and a long tongue. Her skin is even greenish.

- Overly-Long Tongue: See above.
- Pokémon Speak: She can only say 'Kero', ribbit in English.
- Super-Strength: But only in her legs and tongue. The rest of her is very weak.
- Token Mini-Moe: Do to her small stature, her and Marise take up the loli spots. Keroko is much cuter though.
