It's been six months since a white-haired man wearing a red coat is living in Vale. As he looked outside through a window, he saw the entire town has been infested with Grimm.

His name is Ragna the Bloodedge.

"Who am I?"

After the events where he was forced to attack Jin and Noel against his will, he was led into an unknown area where he saw a dark energy ball in the sky. He lost his memories when he questioned himself. Just then, a portal opened up near him, sending him to another universe known as Remnant. Unfortunately for him, he landed in Vale where the entire city has been overrun with Grimm.

He is not alone in this situation. Tsubaki Yayoi has been living with him ever since she got sucked by the same portal that transported him in this universe. Originally pursued him to kill him for being the evil that she believes him of and for his attack on Jin and Noel, she eventually discovers that he isn't the evil she believes him to be and that she decided to become his ally. Besides, sticking together is the only option for both of them and Ragna has amnesia, so he doesn't remember everything, including his attack on her two friends.

After looking out the window, Ragna approached the table as he grabbed a map where there are four dots. There are red, white, blue, and yellow dots all over and these are people to locate. He recalled the moment where he was given this map by a woman known as Raven Branwen. Along with this, she gave him a videotape of her observation during the fall of Beacon Academy.

"So, this woman gave you a map to locate four people?" Tsubaki stands up from her bed and approached him.

"Yeah, that's it," Ragna responded.

"Why would she also gave you a videotape?"

"I don't know. Maybe it's a motivation or something."

"Oh... Do you even know who you are, Ragna?"

"No, I don't remember much about myself. Hell, I don't even know what happened before we got here."

"Maybe we should go on this quest. This should help you regain your memories."

"Yeah, good idea, Tsubaki."

Upon hearing his agreement to the quest, Tsubaki looked at Ragna with a smile on her face. To her, he really is a good person under the gruff exterior, either with amnesia or not.

The two went outside and walked their way to the streets, hoping to find transportation that could take them to where the four dots are located. Of course, they ignored the Grimm that are looking at them.

A conversation took place.

"How much do you remember so far?" Tsubaki asked.

"I remember... about saving someone," Ragna replied.

"Like Noel?"

"Yeah, like Noel, but I don't know why I'm doing this."

"It's good that you do this because you care about her."

"I think that must be the reason."

"What do you think about Jin? He's your younger brother after all."

"I'm... uncomfortable if I think about him. Don't know why. Is it because what happened between us when we were kids? Can't remember anything at all."

As Ragna struggled to remember anything, he and Tsubaki are being surrounded by Grimm. There are four Ursas, four Beowolves, and one Death Stalker.

"Do you know how to fight?" Tsubaki readies her Izayoi.

"I know how to fight, but I don't know how did I learn to," Ragna readies his Blood-Scythe.

"Fair enough."

A Death Stalker is about to send its stinger on their direction, but they act fast enough to dodge it. Next, Ragna transforms his sword into a scythe and swings it from above its head to slay it. Tsubaki take on two Ursas as she charged on one with her shield and unleashed a combo on the other one with her red small sword. Of course, she stabbed an upcoming Beowolf from behind her back. With his weapon in sword form once again, Ragna slices the other two Beowolves on his way.

This leaves both with two Ursas and one Beowolf.

In no time, Ragna performs a very fast, dashing reverse-grip sword slam, then releases two crossing spikes of dark energy from slashing the ground with his sword in reverse-grip to defeat the Beowolf, and Tsubaki summons eight blades in the air and fires them rapidly at the two Ursas to defeat them.

"I guess that's that," she commented. "But how do we get out of the city?"

As she and Ragna walked continued their walk through the streets, they found an airship outside near the city.

"Guess this is the answer."

They managed to get the vehicle working to send them flying to the sky and out of Vale.

So far, so good.

Tsubaki will be driving the vehicle as Ragna looks at the map.

"So, who do you we go to first?"

Author's Note: What do you think? This is my first BlazBlue and RWBY crossover fanfiction story. The version of Ragna for this story is when he has amnesia after the events of Chronophantasma. The story took place after Volume 3 of RWBY, so I'm trying to balance both works on where they are now. This is how I think Volume 4 would be like and combining it with the plot from Central Fiction.

There's also a crack pairing between Ragna and Tsubaki.

So, who should they recruit first? Judging by Ruby going to Mistral, going to her first is out of the question, so they only have the option to recruit Weiss, Blake, and Yang. Once they got them together, Ruby is last.

Comment on who should Ragna and Tsubaki recruit first.
