The Boy You Left Behind (RWBY Harem x O.C)

The New Family

--In the forest, 10 Years Earlier-- 03.45 AM.

A young man is seen running along the trees as he keeps panting and looking back. that man is Orion, who just ran off from the Rose family home. A few minutes went by and the kid slept under a tree on the cold. Then a Beowolf Grimm attacked him. But before it could do any harm to the poor boy. A girl had killed the Beowolf and took the boy to her home. Her name was Nixium Armilla. Daughter of Fraxium Armilla and Freya Armilla. After a day, Orion woke up, confused at where he is.

???: Hey Dad!! He's awake!!

??? 2: Oh. Let me go to him.

The girl scooted aside for her father to look at Orion.

??? 2: Hi. I'm Fraxium Armilla. This here is my daughter, Nixium Armilla. Nice to meet you.

Orion: Yeah, you too. i'm Orion by the way.

Nixium: So what's your surname?? like you family name.

Orion: Oh it's Rose.

Fraxium: Oh he's part of the Rose family. I'll tell them to go and pick you up then.

Orion: No don't please! i don't wanna go back.

Nixium: Huh? Why?

After being asked that question, Orion started debating himself whether he should tell or not. But as thanks for saving him from the forest, he told them everything. After he told them that Fraxium kept his calm while staring at him and Nixium was wide eyed. Then Fraxium asked a question that blew Orion's mind.

Fraxium: How about we become your family?

Orion: H-huh? Are you sure? i mean i just ran off from my own family.

Nixium: Well that's cause they abused you, we won't.

Fraxium: Yeah kid. we won't.

After hearing that, Orion finally accepts and they lived as a family. Reborn.

--Back To Present Day--
{Initiation Day, 6 A.M}
Orion woke up due to his alarm. he then got dressed and took a bath and started working out. Not knowing someone was stalking him.

After his work out, he went back to find alot of the students are already up. He then got dressed to his usual clothing and went to the Initiation.

After a brief speech from Ozpin everyone was sent down to the Emerald Forest to look for the relic piece. Everyone was going in teams but Orion just stood on a tree eating beans while listening to Wherever You Are by again, ONE OK ROCK. a few minutes of nothingness later he saw that his dear sister Ruby is in trouble and about to get stung by a Deathstalker. He used his hood on the coat and summoned a scythe and banishes the absolute hell of the Deathstalker with hundreds of slashes. Then he teleported to a relic piece and teleported back to the tree he was in. After a few minutes of waiting, He then decided to go to the hill.

After the presentations of the teams he got in a problem. He didn't have a team! After a bit of protest, Ozpin made him he fifth member of a team. Team RWBY. At first he didn't think too bad about it but then, he remembered Yang. Then he just went to the dorm with his hood covering his face and entered. Then...

Ruby: Oh hey you're the guy who saved me on the initiation earlier! I'm Ruby Rose, that's my sister Yang, that's Weiss and that's Blake! So why're you here?

Orion: Oh i uh.. i live here.

so i guess that happened.....
Welp enjoy your stay there my friend.
