So... kinda stuck between 3 character ideas. I'll put them all here in this post and go with whichever of the three seems the most popular
The first character is Eari Uzumaki. She has the very same shade of red hair that the Uzumaki Clan is known for and has yellow eyes, but wears a rainbow colored attire. Eari shares certain personality traits with her most notable descendants in Naruto and Boruto, but unlike either of them, she can't fire off Ransengans or deploy Shadow Clones, among other things. This is because Eari actually has no affinity for ninjutsu whatsoever, and must rely solely on taijutsu and genjutsu to triumph over her enemies. Eari's most prominent technique is a variation of Uzumaki Barrage that uses her genjutsu to achieve the things the Shadow Clones would achieve for Naruto's Uzumaki Barrage. She has a medium level of chakra available, but burns through it worryingly quickly due to poor chakra control.
Second char is ShinriKiyaru Aburame, whose first name his teammates tend to shorten to Shinri. He wears a kimino and has an androgynous appearance to him, with shoulder length black hair and fading white eyes. Shinri is physically blind, but his heightened hearing and sense of touch provide him a good understanding of his surrounding, as do the insects that are housed in his body as per the Aburame Clan tradition. These specific insects are aquatic in nature, which support the possibility that Shinri will have an affinity for Water Release Jutsu. His battle style has a balance of offense and defense to it, and he seems capable of analyzing his opposition on the fly and adapting accordingly. His vast level of chakra control is more than enough to mask the scarcity of his total reserves.
Finally, Shika Nara. Her brown hair is tied in a single ponytail, and she has emerald green eyes. Her breasts are relatively large for someone her age; they're even comparable in size to those of fully grown women, which is something that Shika takes particular pride in. Aside from the coveted Shadow Imitation Jutsu, Shika has access to a handful of powerful Jutsu that were passed down from her sensei, who was particularly known for the utilization of Fire Release Jutsu. Shika is an arrogant kunoichi, who can also sadistic towards other battling shinobi, but at the same time, she feels as though she has a lot to prove; not just to Konoha, but to all five Great Nations. Shika has a massive pool of chakra, and her level of control is satisfactory for her purposes.

So yeah, those are the three character ideas I have: two Reds in Eari and Shinri, and a Rival in Shika. Which one sounds best to you guys?
