This section will explore Fuuma's relationships with the other characters of X that he interacts with. It should eventually be fairly extensive, since Fuuma has touched nearly all of the important players in the series.
- His family: Kyougo, Saya and Kotori
- Kuzuki Kakyou
- Nataku and Kasumi Karen
- Nekoi Yuzuriha
- The girl at Ebisu (aka Frog Girl)
- The Sakurazukamoris
- Shirou Kamui
I know these are hardly the only ones worth mentioning. These are just the ones I'll start with.
