It's been quite a while since Kuroto was just a kid, and as of now, 26th October 2009, Kuroto has turned thirteen years old. With basically the whole world celebrating this day- as not only was this his birthday but also the day the humans got their world back.
Since his first mission Kuroto has been informed to "kindly not level the cities and mostly do whatever he wants in the training ground built for him". Not like he cared, as mainly all he cared about was how he had been mastering his abilities.. slowly even perfecting them at times. Feeling really proud but at the same time he knew he had to improve.. so he kept going.
That's how it had been for the past years. Nothing much changed in his school, friends group, or anything, all that really changed is that the world and him got much stronger, and Kuroto drawing nowhere closer to the third passive. With curse bases falling left and right- it was about time that their race may come to an end.
The main topic is.. will that happen before or after the reappearance of Sukura Goen? Nobody knows for sure.. but even if he appears in time, Kuroto Ryuzen is still in the play.
Even though he won't be at his full potential by the time the great king awakes, his power could still overwhelm even Sukura. "The only thing left is to let time do the job, and carry on with it's flow". At least that's how most humans would put it.
