Kaoruko has blue eyes, wears glasses and has dark brown hair attached in a short ponytail.
- Ichika Orimura - She, like other girls, has a fascination for Ichika. She even told Ichika that he has to go on a date with her to "pay" for constructing Kanzashi IS.
- Tatenashi Sarashiki - in the past, Kaoruko had given Tatenashi many suggestions on building her own IS.
Infinite Stratos & AbilitiesEdit
It can be deduced from Tatenashi's comments about her help that Kaoruko is the elite of the second year, and hence, her abilities at constructing and customizing an IS are very good.
In the past, Kaoruko and Nohotoke Utsuho had helped Tatenashi build her own IS. The two were also part of the IS maintenance branch and continue to maintain it up to the present day.
