A/N: here's chapter 13 for ya guys, in response to my question on the last chapter I'll be adding Nora to the harem. 

 A week later, Professor Goodwitch's Class 

"That concludes our lesson for day, now would anybody like to have a match today"? Professor Goodwitch asked looking around the classroom. The silver haired male from yesterday raised his hand."Ah Mr Mercury Black and who would you like to face"? Professor Goodwitch asked. "Him". Mercury pointed at Y/N, the class gasped as Goodwitch became nervous, she then shakily said."Maybe you should pick someone else, how about..." "I accept". Y/N said in an uninterested voice before standing up and leaving to grab his weapon.

"Is Y/N okay he sounded off today"? Ruby asked."No he's fine". Pyrrha replied as Teams RWBY, JNPR and CVFY sat down confused at Y/N shift in attitude.The two girls from yesterday sat next to Pyrrha, they looked over to he three teams and introduced themselves."My name is Cinder and this is my friend Emerald".The black haired female said as the green haired female waved at the group, the whole nice act sickened the girls but they had to keep it up, Pyrrha smiled before replying."My name is Pyrrha, your friend is very brave to challenge Y/N".Cinder chuckled slightly before saying."Well yes Mercury as always been reckless but Y/N shouldn't underestimate Mercury he is quite strong". Pyrrha nodded before turning her attention to the arena. 

Beacon Arena 

Mercury and Y/N walked out into the arena and got into the their battle stances. Mercury smirked before saying."This'll be fun"."No it won't". Y/N said in a flat monotone voice, shocking everyone in the stand, Mercury snarled before yelling."Don't underestimate me"! He rushed Y/N and attacked Y/N with quick and precise kicks but Y/N dodged all of Mercury's kicks while his eyes were closed. Mercury's anger began to rise as he threw punches, kicks, elbows and knees at Y/N, who still had his eyes closed, but none of them landed. 

Y/N shook his head before saying."Told you this wouldn't be fun, you haven't even landed a single hit on me. I wasn't underestimating you, you were overestimating yourself". He opened his eyes and they glowed blood red, he then vanished in a cloud of black smoke before appearing behind Mercury. Y/N sheathed his sword and walked out of the arena.

Cinder and Emerald sat there with their eyes wide open and mouths agape. Cinder quickly recovered before saying."Y/N is so strong it was as if he was toying with Mercury"."That's because he was".Tiki replied, Emerald recovers from her shock as well saying."So how strong is he then"."No one knows, he never gone all out against anything or anyone". Kamui said while Corrin then added."The hardest I've seen him fight was when he fought Winter Schnee but even then he wasn't really trying". 

Cinder, Emerald and Mercury's Dorm 

"Well that was a terrible idea, I thought if I challenged him I would be able to gauge his strength but he didn't even try". Mercury said as he lay on his bed groaning in pain."I think it would be unwise to engage in any fights with him, from what his friends have said he maybe too strong even if we get her powers". Emerald said as she started to panick. Cinder remained quite as she was thinking about Y/N 'he's so strong and handsome, I wonder if ...' she was brought out her thoughts by a sharp knock at the door. Emerald got up and answered the door. 

As Emerald opened the door she was shocked by who she saw."Hey Y/N, what brings you here". Emerald said in a shaky voice, she was blushing  fairly heavily 'she looks cute when she blushes it's a shame she's been caught up with the wrong people, same with Cinder really '. Y/N smiled, which caused Emerald to blush even more, and said."Can I come in I want to talk to you and your team about something"? Emerald then nodded before sidestepping and letting Y/N in. 

Y/N sat on a chair while the other three sat, or in Mercury's case lay, on their beds."So Y/N what do you want to talk about"? Cinder asked as Y/N sighed before saying."I know your not students from Haven Academy and I know who you work for". The three then went wide eyed, Emerald and Cinder readied their weapons."Who told you I bet you it was bitch Neo"! Cinder yelled, Y/N looked at her his calm expression disappearing for one of anger, he then said."Watch your words Cinder, Neo told me nothing". Y/N then raised his power causing everyone in the room to become shocked at the power Y/N was giving off. 

Mercury jumped of his bed and charged at Y/N only for Y/N to punch him in the face, Y/N then followed that up with a leg sweep with enough force to break Mercury's legs. Cinder and Emerald looked at Y/N in horrors, Cinder and Emerald lowered their weapons as Y/N stood up and looked at the two females who were now scared of him he sighed before saying."Look this path you walk is a dangerous one that will lead you further away from the goals you want in life". Y/N looked at Emerald and said."I sense the desire that you do not wish to return to your former life you just wish to be happy. Ask yourself this will killing random civilians make you happy"? Emerald became stunned as the words that Y/N spoke ran through her head 'he is right I want to be happy but this world has been cold to me and Cinder is the only one to ever help me but then again I don't really want to do this for much longer my happiness is more important '. 

Y/N turned to Cinder and said."The power you wield is not yours, you crave power because you felt helpless once and do not wish to feel like that again. I can relate to you on that front, I was helpless and powerless once but stealing someone else's power still means that you yourself are still powerless. You need to figure out your own strengths and build from there". Cinder was shocked and almost touched by Y/N's words 'he really is amazing but this power I have is great and I want to keep it but I also know it's not really mine. I just don't want to powerless again, I couldn't save my family back then '. 

Y/N began to leave the room but Cinder shouted for him to stop, Y/N turned around as Cinder said."Why are you trying to stop us for begging criminals". Y/N smiled as he replied."Because I believe that some people deserve a second chance to redeem themselves, also you two are really beautiful and I couldn't let you ruin your lives anymore". Cinder and Emerald blushed, Emerald then asked Y/N."When you asked me if I was okay with killing civilians why didn't you say innocent civilians"."Nobody is innocent, there are merely varying levels of guilt". Y/N said a serious tone before adding."I'll see you girls tomorrow".

A/N: and that ends chapter 13 guys. Question time once again, should I add the Team RWBY's mums ; Kali, Raven, Summer and Willow, Weiss's mother, into this harem.
