Personality
Honoka is an over-confident and friendly leader who always acts before she thinks in battle, however, displays a serious persona as a leader. Since becoming a Muse Ranger, Honoka wanted to continue her father's work of how Muzon connects one with another. As the series progresses, Honoka became mature and dependent leader, realizing that her father and her team's father died to protect those they love. She gets tired very easily and is rather clingy, mainly on Umi and her younger sister, Yukiho.

Honoka is the most affected among her team of losing her father, despite not knowing him, and wants bear the pain alone. This proved true as she and her team witnessed the ultimate sacrifice their fathers did against Dr. Yaruzo Zarak and his Viruszoid as she cried out her father in Mission 8: A Travel To The Past.

Honoka is plainly oblivious to Tsubasa's feelings for her, often ended getting dumbfounded by it. She later realizes this in '''Mission 40: μ's And A-Rise Combine! '''and confessing her feelings to her in the season finale.

Her personal catchphrase is "Faito Daiyo" (meaning "Let's Fight On!"), which helps her give motivation to fight in battle. It is later used by everyone else on the series.

Background
Before Honoka was born, her father, Tazuki Kousaka, was the head professor of the Muse Agency. On the day when Honoka was born, he and his eight colleagues imprisoned Professor Yaruzo Zarak in an alternate dimension they created with the energy source Muzon, however, it costed them their own lives. Thus, Honoka grew up not knowing her father and her mother keeping it a secret from her, fearing of losing her daughter just as she lost her husband. Her young sister Yukiho was born two years later.

She is childhood best friends with Umi Sonoda and Kotori, who are also daughters of the Muse Agency scientist. Unknown to Honoka, both of her two best friends are undergoing training to become Muse Rangers. She somehow gets suspicious of her mother throwing away letters without even reading it, as they are recruitment papers. Some time later in her childhood, when her school gets attacked by alien convicts and her being held hostage by the leader. She was then saved by Kanako/Momori Z 1gou who fought the leader and helped her return to her mother and friends. Thsi event inspired Honoka to become a hero one day, unknown to her that she will really become one. (Tokumei Sentai Muse Ranger VS Momoiro Clover Z)
