Mass Upload! Sketch: Rokuro

Aka, Naito of 5th-6th gen!
Rokuro here is one of Shuyri's descendants. She's very reserved, not unlike Kage, although where he was cold, Rokuro becomes ruthless after her Knights of the Round training.
Yup, she's part of a group called Knights of the Round, for those wondering. Ten different knights, all with differing personalities and skills, of course.
Rokuro is the 6th knight.
Funny, I never noticed before... The number of knights coincides with the number of demonic generations of Ceres! xD
Technically, Kaskuri is of a future gen, and Shoraku of the extra generation could be counted as anotherpair of gens, tho. Yay~ xD

~Shadow R/B
The knights, in order of rank and appearance (Knights rank differs from demonic rank, btw), are:
[1]0- Zero Laguna (Ice Knight)--Wolf
1- Ichiru Mikami (Flame Knight)--Lummox
2- Eiji Kazura (Earth Knight)--Lizard
3- Mitsuru Tsuna (Thunder Knight)--Cabbit (It's Aura!)
4- Manami Yuriko (Water Knight)--Seal (Female)
5- Kameko Yamiko (Dark Knight)--Bat (Female)
6- Rokuro/Naito Suzaku/Sumaki (name change; Shadow Knight)--Wild Dog (Female)
7- Arisa Nana (Wind Knight)--Hawk (Female)
8- Hachi Kazura (Nature Knight)--Racoon
9- Amaterasu Raito/"Laika" (Light Knight)--Chimera (Female)

Yeah, I tried making the gender ratio the same, although Knights exist outside of this group, like Gunji.
There are more Knights outside of these ten (obviously), although they aren't officially recognized HERE, as they came before these guys. Those knights are Skye (The Raven Knight), Kage (The Phoenix Knight) and Lyre (Quezacotl's Knight). Yoru might count, as he gets a Knight-like ability (Red Ice; basically, ice bombs) that renders him the "Ragnarok Knight" in the extra scenario.
And yes, Rokuro does end up having a kid with Zero. Recall Hitori? If not, he's one of the demons with Void magic that basically makes it so that he has to be alone or with a being without magic, otherwise his magic will auto-kill them by absorbing their magic. >~<U
