Gradually making his way up to the storage room of plans, Kuroto enters the lift, and sets it up to the storage floor. Then, some curses in the lift ask "Why do you need to go to the storage room?, boss said you can only go there if it's important". This was his first time hearing about a "boss". Not to look too suspicious, he replies "Boss told me to fetch the plan blueprints for him so that he could make some changes".
One of the curses replied in suspicion "But i just came from the storage room for that exact reason- wait a second.." he notices that he shaped like a human. "INTRUDER!" the curse exclaims as it presses the emergency alarm button in it's pocket. Kuroto, realizing the danger, acts accordingly by slaughtering all of the curses in the lift and speedily moves to the storage room on his own.
Alarms were blaring everywhere- no time to waste. He searches around the room, finds the plans, and quickly stores them in the backpack he was carrying. After storing the plans, a slight grin appeared on Kuroto's face. From then on there, it was his time to shine.
First, the top floors. Not even grade 1 curses could sense him, and he kills off the top 10 floors with ease. Alarms still blaring everywhere, he slowly makes his way down and slaughters everything along the way, reaching the ground floor. There, hundreds of guards armed with special weapons stood waiting for him.
"Perfect" says Kuroto as a black sphere appears from behind him. "Unimaginable technique: Black" he exclaims as black consumes every curse, every weapon, and everything else along the way, not to mention totally leveling the base itself.
When it's over, Kuroto stands in a giant land full of rubble. "Well.. it was fun while it lasted" Kuroto sighs.
As he turns to head back.. something jumps out of the rubble.. diving directly at Kuroto. He easily gets out of the way, staring at the curse, he says " You must be the boss, a semi special grade curse. I guess your gonna have to die too". The boss laughs, "While if it isn't the man himself.. Kuroto Ryuzen. I must admit that you are very strong.. but don't think that I'll die so easily."
Kuroto slightly smirks, "Wanna bet?", to which he got the reply "Bet".
