Hello, Hello. I realised I never got around to explaining the levels our crossover characters are actually at. Here's the lowdown of what they have, turning TMC into RWBY terms:

Paige Woods has her soul powers, but her Death State/Soul-Forms is functioning as her semblance, since after contacting Maiden Moon, Moon's no longer giving her gifts to her passively. Paige's body CAN be killed, but she still has the failsafe of waking up in her home if she would have truly died.

Angeline is currently in a soul form, and has access to her self-created power, Stigan Apotheosis. Her new catch, as noted earlier here, is that Aura overuse will remove her from Life.

Blair Hardy's "Blood Bond" used her dying phrase "hold my hand and see we are one." that showed the past from her eyes. To move Port, I had briefly pictured her going all out in the hallway air-fighting during the fight. The series never gave a limit, but she did control ten soulless creatures in her backstory, and controlled two humans with her full effort before losing her mind. I'd say she can't trump Jax in quantity, but her quality would easily beat his.

Cassandra appeared to have no extra gifts. She was just a completely normal university student girl when Paige met her, and all throughout their relationship she had no signs of being supernatural. I assume her "ability" was her being able to keep her humanity, and her sister's latent defense and healing.

Nyx is using the only supernatural thing they ever did as her semblance. "Plain Sight" allows her to see. As she bypassed a minor god's presence nullification, it's only really good against illusions.

It was late, but Paige was busy doing interesting talks about careers and things.

Paige was in a musing mood. "What's the worst thing you ever fought?"

"Well, there was one especially dicey incident where my team was fighting against a particularly terrible Grimm:"

He paused, his moustache rustling in the winds of the past.

"Leviathan."

His audience of one twitched slightly, then leaned forward.

… "Seriously? Are you trying to be funny."

"This is no lie! Would you like to hear what happened? We have some time."

"Gladly. I'd like to know how to kill a legendary creature of myths."

"Well, it all hinges on how willing you are to build the same boat 46 times. Before I happened on the idea, we had been in a rather perilous situation-"

The young woman watched in astonishment hearing his long, long tale of strenuous victory, culminating in one of the most impressive attrition takedowns she had heard of… then noticed him… trail off.

The professor became hesitant. "You shouldn't try this yourself. It's too dangerous. It's much too risky for anyone to try, and I am possibly the only person who was able to achieve it."

"Are you… humble bragging? You didn't just make this up, right?" she accused.

….

..

.

"No. I didn't. I faced against a Leviathan with this tactic, and won."

"Professor. May I be candid with you?"

"Why, gladly!" he chuckled.

"Did I do something wrong to you? I heard that you were basically the most boisterous teacher in the entire school. Why are you getting all serious and worried after I started working with you?"

… He paused, and went over to his desk. "Mrs Woods. I was quite surprised you chose to work alongside me. Thus, I chose to make a good impression. However, your arrival just so happened to coincide with my learning of quite a few new things about the Grimm."

…

Paige looked at his expression, then glanced at his significant pile of notes, and her eyes widened in a look of horror. "Oh no."

Port turned away from her face. "Yes. So, I apologise if you expected anything differen-"

"Professor Port. May I presume you learned knowledge about the Grimm that would cause your teachings to be inaccurate?"

Port blinked.

"Uh… Yes. I did."

…I did, in fact. …Why does she look like I said I was dying?

"Recently, I have it validated on a trusted source that Leviathan are capable of releasing incredibly powerful beams of energy that can destroy a battleship with ease."

"-and I somehow did succeed years before, and killed one with my team, and 49 identical boats."

She frowned, then commented. "So, your new knowledge invalidates the older information. Thus, you are proven wrong. Why is that leading to your change?"

Port looked at her.

"I taught the captain."

….

...

They both were silent for a minute. Port spoke in a dry voice. "To go to less awful thoughts, what is yours?"

Paige snorted. "The worst thing I ever faced? Team, or alone? Fighting with Atlas…. was my boss."

"Hah! So, you didn't appreciate Atlas's rigorous structure?"

…"Huh? You know about Atlas?"

"Certainly! They're a very talented and courageous group of people. I personally respect them, even if I feel less confident about their choice to use unawakened people as soldiers."

Paige smiled at that. "Good to hear the old team's still going strong."

"Now… worst thing I personally faced….. was…. uh… My older sister-in-law."

He nearly fell at that, rocking with laughter. "I believe you are an even worse example of a humble bragger if my fight against a Leviathan was humble! No Grimm has ever been a worthy opponent to you! Only… your sister-in-law? If I had the bravery to go against people like that…"

Port had to stop from losing his breath, having to pound his chest to get back to stability. "Now, you seriously tell your tale."

"Really?"

"You heard mine, so I can listen to yours."

"Ah… okay." she whispered. "It took about ten years in total to actually kill them, but the most important part was the first time I single-handedly faced them."

Port nodded once, and tilted his head slightly.

"I had nothing, no magical anything, which really terrified me after I got her to the floor. All I had was an axe and my shotgun. It took ten minutes to get them to their knees, since she apparently was durable as a brick wall and she could just… heal herself? I remember the first shot hitting her dead in the chest and thinking that the world was going crazy, but I knew she was responsible for capturing and sending those creepy old mutated fuckers that you couldn't even call beasts after me. I just wailed on her until something stuck, and then kept going at it until she would give up and drop all the fire left in her."

Port was quiet, he leaned back, clutching his hands to his seat.

-but he then took a breath, stood up, and walked over to his assistant.

"Mrs Woods."

"Is it acceptable if I quickly finish?" she asked.

…

"Okay. First, she's stupidly durable, she just… healed, and she had been capturing those freaky eyed things after me, right? So, I got her to her knees, axed her like the bag of rotten meat she was until she got up, and ripped my hair out and tried to strangle me. Eventually managed to get her kicked out of the window, then burned her to death and threw her into the ocean. Done."

"Mrs Woods."

She looked up at him. "Yes?"

"You… killed an aura trained person."

Her eyes widened. "Uh… yes? Now that you say it, that does sound like Aura."

"An aura trained person who captured Grimm and tried to kill you with them on multiple occasions."

He watched her eyes dart around, obviously worried… She muttered rapidly "Uh… wha-What? Professor. I don't kn-"

…

Port saw she was trying very hard to get out of the conversation.

…

…

Until she started thinking a bit more. He could tell the exact moment, since it was rather obvious.

She stood, bashed her head with a hand, and spoke with shock. "WAIT."

She fell back down, put her head in her hands and groaned. "UGH. Nobody ever took me seriously for so long that I just… forgot that there's all sorts of people that literally teach people about this stuff. I worked with Atlas for years! I spent at least three years fighting unnatural beasts! I met a girl that can run on rooftops and turn into romcom effects!"

Port quietly tried to comfort her. "I think it's worse that your sister in law did such an incredible dangerous and problematic thing to you, and you were an untrained regular civilian."

She snorted. "I wasn't regular. I was a little freak."

He raised his brows in a concerned stare.

"Well, I'm trained now. All's well that ends well, and all that."

"I presume you gained your abilities during this period, correct?" Port asked.

…

…

Paige froze. "Why do you say that?"

"Your hair." he noted. "Currently, it's grey, but when you used your ability, it was black.

"Huh… you rea-"

"-I think I notice it when someone is hit so hard they lose all pigmentation in her hair."

…

"Yeah… good point. That makes sense. Normally people don't notice."

"Also, the most traumatic point in your life is when you fought your far stronger sister in law, presumably to protect your partner, and she ripped out all your hair in a stressful fight to the death. This means you definitely had physical contact."

Port paused for emphasis, and then gestured dramatically. "If you, while fighting a person related to you by the blood if your partner, awoke an ability called "Blood Bond", able to share your experience, even controlling the target, when fighting the woman that controlled your life for a decade…."

"That makes perfect sense on how you'd be able to beat them so easily without any training. I only have one issue with this, though."

Paige waited for the chance to do some question dodging. She didn't get any, as Port fired his last question like an emotion seeking bullet. "Blair?"

Yeah?

"Blair was my younger sister-in-law. We never had the chance to get close."

"But you included her in your list of relations, and named your semblance after her, and also talk to your semblance like it's a chi-"

…"-ld."

…

…

He quieted. "I apologize for my thoughtless behaviour. How… young?"

Uh… 1942? I remember a new book written by Father, and it was dated 1942. I don't know it well now, though. Father just talked about God forsaking the Empire, then us. He did show me when the moon made the sun go away. There was lots of girls screaming, back in those days. I think I just lost track of who did it. Damn. This is hard. …Paige. Any ideas how old I am?

"I was never able to find out."

…

"I… will stop my personal questions. Do you wish to discuss my theoretic plan with the headmaster at a later point?"

"That's perfectly fine with me. Apologies about today's lesson."

He replied with "It's fine. I've faced worse things before! It would be a shame if this is what finally bested me!"

The two of them left the room, and prepared to rest for the next day's work.

Paige walked to her room, and prepared to go to sleep.

… It took her a minute to realize someone locked the door, so she just went to the lit office a door down.

..

..

..

…

"Hello, Branwen. You are still here?"

Branwen looked up at her, surprise evident.

"Did you… not use your scroll at all today?"

… "Nope."

…

The two watched each other for a moment.

"You… do know you have a proper room with a proper bed assigned to you. You don't have to sleep in the first room you slept in."

Paige turned to the wall. "It's habit."

… "Wh-" he started, "-Actually… I don't really care that much about your weird proclivities. Do you want the key to your new room, or are you going to try to sleep on a table?"

"I'll take the room."

… "Do you want help finding your room?"

"I'm fine."

Paige walked, checking her newfound digital device, and eventually managed to wander around long enough that she found a sparsely decorated room, with a set of four beds, and a few assorted storage places.

"Spare room, I guess."

She breathed out slowly.

… I'm not in the mood to save anyone new, Moon.

Paige fell onto the bed with trained efficiency, and was asleep in a few moments.
