Kou seems to be one of the more cheerful characters in Arcaea, as she, Hikari, and Hikari (Fracture) are the only partners seen with genuine, blissful smiles, and many of the songs in her dedicated pack, Crimson Solace, are very upbeat.
Stats by Level
- Kou's name means "crimson" in Japanese. This is why her character design uses mostly red and pink, and her pack is called Crimson Solace. It's also the main color tone of Nirv lucE.
- Lethe and Kou's stats for FRAG and STEP are completely reversed.
