Koihime†Musō Edit

The leader of the Go faction, she is first introduced during the the anti-Tōtaku campaign as part of the alliance.
After her defeat, she gives herself up as a punishment for her incompetence in being a ruler. However, she begins to develop feelings for Kazuto as he accepts her as simply a girl rather than a ruler, and for always treating her and her subordinates more as friends than prisoners during their time as captives. It is also slightly hinted by Ukitsu and even Sonken herself that she developed a crush for Kazuto much earlier, possibly during their alliance against Gi.

Go Route Edit

Her older sister Sonsaku takes her place as the leader of Go faction. Her hair has also been greatly lengthened. However if Kazuto joins the Go faction, Sonsaku is eventually assassinated early in the campaign, and Sonken takes over with a heavy heart, cutting her hair upon doing so. She refused to accept Kazuto at first, but later falls in love with him.

 Moe Shōden Edit

Shin Koihime † Eiyūtan Edit

Shin Koihime † Musou -Kakumei- Edit

Son Go no Kechimyaku Edit

Ryū Hata no Taibō Edit

Anime versionEdit

Second sister of the Son family, unlike Sonsaku, she is less ruthless, uneasy about herself, and more kind-hearted. She worries about how her sister's wars are affecting everyone while, unknown to her, her sister is doing this for her sake. Sonsaku has chosen her to be next-in-line to the throne; she knows that she will be a better ruler who will heal the wounds the nation has suffered from the wars.



Unlike her elder-sister and mother, she does not like to wage wars of conquest and instead prefers peace. For that reason, she has an uneasy relationship with the Go strategist Shūyu, who sees her as lacking ambition and constantly reminds her to follow Sonken's footsteps and carry on Son family's pride by conquering China. Due to Shūyu frequently criticizing her for not fulfilling expectations as a member of the Son family, she feels overshadowed by her predecessors. She is insecure about her abilities as a ruler and questions herself whether she's fit to inherit the throne.


Initially, due to the pressure put on her as the ruler of Go, she tends to keep away from romance. However, her interactions with Kazuto made her soften up. Due to Kazuto's influence, she eventually becomes willing to participate in group sex. 

Skills and Abilities Edit

Swordsmanship: She has received training in wielding a sword from Kannei.

Weaknesses:  Edit

  • In the first VN, despite possessing decent fighting skills, she has not fought in an actual battle. This lack of real combat experience caused her to fail to land even a single hit on Kan'u before being defeated.


  • All three of the Son siblings's true names have connection with the lotus flower; however Sonken's true name means something akin to "Lotus Magnificence", which is less literal.
  • A few of her sprites and artworks on the official website of the first VN show her with purplish-red eyes.
  • In Shin Koihime†Musō: Otome Taisen Sangokushi Engi she wields a tonfa alongside her sword.
    • On the cover art for the PS3 version of the game she is shown wielding two tonfas even though she is limited to only one in the game.
  • In the animated opening of Sengoku†Koihime: ~Otome Kenran ☆ Sengoku Emaki~, Ashikaga Kazuha Yoshiteru summon the weapons of various Koihime†Musō heroines as projectiles for her attack; among those is familial ancestral sword, wielded by Sonken Bundai, Sonsaku, and Sonken Chūbō.
  • For some reason, even thought she didn't cut her hair at the end of the Shoku Route (true route) of Shin Koihime†Musō she has short hair is Shin Koihime†Musou ~Moeshouden.
  • Renfa took first place in the poll of the most popular character in the story company Go.[1]
