upper 6 could smell a strong scent from the arc. one he's never seen before. as he knew it would be fun fighting arc but also he would become stronger. he charged at arc but arc got up and blocked it. arc then kicks upper 6 and upper 6 breaks 2 bones from it. but when 6 realized how strong arc was he started trying and kicked arc and sent him flying. but arc regains balance and tries using his own ability flow calm. and he manages to cut 6s arm off. but when he uses the attack he leaves himself wide open. so 6 took that as a chance to punch arc in the stomache and break his rib. Then 6 uses 1 of his abilities and packs the power of 10 punches in to one. and he breaks arcs left arm and damages his stomache to where it is harder to breathe and he gets dizzy. Arc then uses an ability he was taught the clash. he uses the ability and chops 6s left leg and damages his bones. while arc is about to pass out he tries to heal himself by changing the way of his breathing. but when he tries to do it he coughs out a massive amount of blood and realises when 6 hit him his breathing was changed and he couldn't use techniques with it. He then tries using his full power but he realises if he uses it in the condition he would die. so he had to think of something else.Then arc realises when 6 charges at him he has a blind spot. so as he was thinking about it 6 starts rushing at him. arc was able to hit the blind spot and 6 threw up blood. then arc realises he had stolen a poison bottle from the castle and he grew up not being affected by poison. he secretly puts the poison in his right arm without 6 seeing him. and arc also noticed that there was blood on 6s fist and now there isn't that can mean he drinks the blood or his hand digests it. he realised a weird hole on 6s hand when 6 punched him.so while thinking he sees 6 already behind him and let's 6 hit him so 6 can digest the poison. 6 digests the poison and falls to the ground. 6 then becomes weaker and arc rushes towards 6 and sees that 6s veins are popping out and his face is turning purple. and arc rushes towards him and before he could hit 6 upper 6 used his ability and commited suicide. arc didn't know why but he thought he saw 6 crying for a second right before he commit suicide. upper 6 knew he would be considered a baby if he showed emotions during a battle. but arc decided to rest for a month so he could heal up and then we would start training again.
