Kikkawa Kiku

One of the three sisters and also the second oldest of Mouri's daughters. Her role in the family is as a cooking-maid, she is responsible for monitoring Motonari's foods due to his health issue.

It's stated that she was married once, though divorced because of several reasons, with one of them being the husband was afraid of her eyes. Due to that marriage and her father's influence, she is only interested with strong men, and will only serve under someone who is able to defeat her in one-on-one match.

Just like her sisters, she loves and respects her father, she always believe that Motonari is the strongest man alive, with or without the curse.

Aside from cooking, she is also implied to be an expert in assassination.

Sengoku Rance
Kiku 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.

She was once trying to teach Kou how to make proper dango, but the result became creepier than what she initially expected. Seeing how atrocious the killer dango is, Kiku assumes that Kou may have a natural talent to be a master assassin, with her assassination weapon being her killer dango, in which Kou obviously refuses.

In the epilogue, Kiku was mentioned by Kou as the one who made the dango with Mine.
