Hachiware is the sunshine of the group. Whenever Chiikawa gets scared or overwhelmed, Hachiware is usually the one trying to reassure them. Hachiware tends to look at things positively and is much more comfortable communicating with others. They're also surprisingly intelligent and capable. Hachiware can read, solve problems, and often notices things that Chiikawa doesn't. But Hachiware isn't permanently happy. They can also become frightened, sad, or hopeless. That's what makes their character more interesting, the optimism is something they actively maintain rather than something that means they never suffer.

Personality: calm, mature, laid-back, experienced, mysterious, independent, and food-loving.

Kuri-Manjū is probably one of the characters who feels the most like an actual adult. They're usually quiet and composed, enjoying food and drinks without making a huge fuss. Unlike Chiikawa, Kuri-Manjū doesn't seem easily frightened.

Personality: strong, serious, disciplined, responsible, experienced, intimidating, but ultimately kind and caring.

Rakko is one of the strongest monster hunters in the setting. They're an experienced senior figure whom Chiikawa admires greatly. At first glance, Rakko can seem intimidating and cold, but they're actually quite caring. Rakko is also one of the characters who approaches dangerous situations much more seriously than the main trio. In the Mermaid Island storyline, Rakko becomes particularly important because of their experience and cautious nature.

Personality: chaotic, fearless, impulsive, eccentric, mischievous, unpredictable, confident, and surprisingly competent.

Usagi is basically the chaos incarnate of the trio. They communicate mostly through strange noises such as:

“YAHAA!”
“URAAA!”

Usagi loves food, frequently acts without explaining themselves, and does things that make absolutely no sense to Chiikawa and Hachiware. But underneath all that chaos, Usagi is extremely capable. They're brave, physically strong, have incredible reflexes, and rarely seem as frightened by monsters as Chiikawa is.

Personality: mysterious, powerful, intimidating, emotional, tragic, and complicated.

Siren is the central figure of the Mermaid Island storyline. She's associated with the mysterious events surrounding the island and the disappearance of its inhabitants. Most importantly, Siren shouldn't simply be viewed as the evil villain. She's one of the characters that gives the Mermaid Island Arc its darker tone.
