Kobayakawa Chinu

One of the three sisters and also the youngest of Mouri's daughters. While seemingly innocent from the outside, Chinu is actually a dangerous killer whose specialty is poison.

Because of her childish and tricky demeanor, she is considered the most dangerous among her sisters. She loves seeing her victims dying slowly, and that's pretty much why she chose poison as her main weapon.

Just like Kiku, Chinu was once married and also divorced right-after.

Chinu is unfortunately met her tragic end during the Demon King's arc. Her body has been sealing one of Xavier's apostles, Genbu, all this time. She died in the same time as the release of said apostle.

Sengoku Rance
Chinu appears along with her family in the first Mouri's introduction event. Just like her sisters, it's only possible to capture her after the all-out battle against Oda's main force.

It's possible for Chinu to eliminate all of Oda's commanders just by simply participating in a battle. It's shown as her poisoning the whole army, causing the commanders to retreat, making it impossible to attack/defend. On the brighter side, it will only happened once in one play-through.

Unlike her other sisters, Chinu is not a virgin and is more open toward everybody, that is including Rance, whom she somehow trusted. During one of her events, she asked Rance to never forget her, implying that she is aware of her limited lifespan due to what she has been sealing inside her body this entire time.

In her last appearance, she is shown telling somebody to wait since she has something to tell to Rance first. Unfortunately, her body exploded and Genbu is released. It's unknown whether her family or Rance is aware of the fact that Chinu is already dead as she never get mentioned anymore.

Only in either Ran's route/Kill-the-Monkey route, Chinu can stay alive, thus making her a permanent ally unlike in the other routes.
