"Curiosity killed the cat..." Keiecho Fleming Russo is the last Yujouki Cheetah---a race that has fought for territory against humanity in the world of Iiaga .In the aftermath of his race's genocide, he was abducted by bioengineers that prepared for self-defense against the world. He was given an incomplete power to negate all pain he's received and a special brand mark made of diamonds. Years after his abduction, he somehow escapes and ends up meeting and becomes the responsibility of two in-training members of the famous Igetasanian militia- Akaiyo Maida and Piper Day. With Keiecho not having interest in blending as a human and making his instinctive curiosity a priority, conflict arises within these three as they come to realize that they must adapt to and explore the Anything Goes era- an era that pins countries against each other for personal gain. "..but satisfaction brought it back."
