Renu Mikai is the gender swaped version of Renu Mika . Though, he is the older brother of Mika.
He almost looks like Hatsune Mikuo but his pants aren't. He also does not have sleeves like Mikuo. He has 2 clips on his left side like Mika. (will be soon drawn because the picture doesn't show clips)
Mikai shares the same personality traits with Mika. but is not shy and draws sometimes. Mikai is a runner and is faster than Sasane An. He is strict on Mika so he'll slap her sometimes. He punches and kick people like Mika. He even hates Sasane An, Mika ex-crush. He spies on Mika sometimes and is suspicious about Sasane and Mika.
