Note that i said 'another idiot'. Haru did something similar his first fight. That being not beating up Ash Roller on his first crash. I hope they also explain that skill Kuroyuki used too, to move her real body while accelerated, because she should have been able to gotten herself out of the way too, unless there were restrictions or she was simply to weak in her human form to 'carry Haru'. That or she was planning all this and all this is just part of her evil mastermind plan to take over the world with a game or something.
I don't see the risk. Cyan Pile is Lv 5 or 6 right? Haru is just Lv 1, and he lacks the arm and the leg to make any physical trap and he has no abilities in related to making traps. Also the amount of life each had at the moment, Cyan Pile had literally 9/10th of his life, even after being bashed by Haru, while Haru down to less than a 1/10th after getting hit by his special. IIRC, Kuroyuki also stated his armor is the type to be weak to melee/physical attacks. If Haru could survive that, I'm sure Cyan Pile could survive a head butt. And lastly, Cyan Pile's color is cyan (obviously) which is between green, which is defense, and blue, which is short range. The game seems to be throwing its own logic out of the window unless there is major variable/factor I'm missing.
I'm gonna assume when you level, there is no level growth, as in you do not physically (in the game) get stronger, you don't get more 'stats' nor do you get a increase-age of actual life points as you level. You only gain a level up bonus, which Ash Roller stated he had one after beating Haru for the first time, and used it on ability instead. Cyan Pile has 5+ level up bonuses, unless he spent all of them on gloating, I'm kinda lost.
