Kokoro (こころ) is a character in the Aozora's Adventure series.
Kokoro is the seventh of the Jetters created by Aozora and Toshi, and began the second wave of developing the Jetters after the completion of Britly. She was the most expensive model to produce due to the excessive amount of detail in her battle suit, resulting in Aozora and Toshi toning down their designs when Ciber began production.
Kokoro was originally developed with a similar mindset to her sister Redd, but less energetic and more calm, varying between being uplifting and cheerful to downbeat depending on her mood. She syncs well with Redd and Moriya, who she spends most of her free time with.
