Chapter 1: The Shadow in the Dorm
In the next chamber, she has a good look around while the villain monologues. It is big enough to contain her true body, which may be necessary.
"Dr. Matusyama -and anybody else who can work magic- can you bring down that magic shield or do I need to smash it?"
Sumeryu isn't psyching herself up for battle. She doesn't have to. She can explode into violence very suddenly and will do so in the next thirty seconds if none of the magic people can dispel the...well the spell.
"The barrier's reflective in nature. You might get hurt if you attack. Just leave it to me." A shadow crossing her face, she steps up and begins to weave complex patterns into the air with the tip of her wand. Just as she knew how to conjure a powerful barrier, she knew how to take one apart. An intricate magic circle forms in front of her, drawing wisps of mana from the air as well as Hanami's own body. Once the magic circle is sufficiently charged, a blindingly bright blast of magic fires towards the barrier.
Rolls
Dispel the Barrier (Witchcraft, Smart); +4 Drama dice - (11d6)
(24665534163) = 45
Barrier Defense - (6d6)
(154264) = 22
Regarding the combat turn though, I'm waiting for any clarifications from the GM in the Open Chat before proceeding, in case my PC knows how to approach this and how not to based on those clarifications (unless they are hidden from PCs).

"Oh... It seems I underestimated you, little witch~ I should have made my barrier stronger; heh, nothing less should be expected from a descendant of the Zarukhim! Bwahahaha!!" He laughs evily.
I'll use the roll you made, and just add the remaining dice to it.
Sorcerer's roll: 1,5,4,2,6,4,2,6,6,1,1.
In the clash of opposing forces, Hanami almost overcomes, the Barrier shrinking almost to meet the sorcerer, but with some effort, he can keep it intact.
"Grr.." He grumbles, seemingly spent, to keep the defenses up. "I indeed underestimated you... The delving down of the second level shall wait. But I warn you: you may delay us, but you won't stop us!" He says, as the seal finally breaks in multiple fragments.
He opens a portal next to him, just like the one that swallowed Aika, a cacophonous circle of lights, like a vitral of stained glass (one with completely random tiles).
"Heh, I'll leave you a little gift though; celebrating our first meeting!" He turns to Aika, still immobilized and seemingly a bit exhausted: "I have been researching what was being experimented on this facility, and have been able to reach a pleasing result already~"
Just before leaving, he touches Aika's forehead with his pointy finger again, "Now dear: be set free! Be the precursor of a new age for monsterkind!" A burst of energy pushes her back, she falls on her knees, her head low and shadowy.
With that, he takes his leave, bringing the Izumi girl with him, her eyes in tears; the portal dissipating behind him, the barrier too, dissolves.
As anyone approaches Aika, she raises her head to meet them, her eyes shinning with a sinister red light, her face contorted in rage, as she jumps on her feet, and lashes at them!
During her dash, she moving in a total animalesque way, she begins to transform: huge wings sprout from her back, definitely larger than before, her whole self seemed taller, in fact, her uniform stretching as it starts tearing partially; her hands turn into terrible claws, and her feet in talons, which shred her shoes.
Finally, her body is covered in feathers, as she takes on a hawk-like body, not so the humanoid hawk-person a Tengu would normally be, but a beastly creature with no traces of humanity.
Anyone with reasonable knowledge of monsterkind would know that this kind of frightening form, where a monster's powers is greatly increased, is only accessible to those who lost a great deal of their humanity, getting stronger and more terrible as they further depart from it.
First Round of Combat:
Aika rushes at the party and, with a powerful fan of her wings and make a pair of miniature tornadoes hurl at the party: one target's Luna, Ling Jing and Sumeryu, as for the other, it target's Ibuki and Hibana. Tornado 1 rolls an 8, the second rolls 9, their DX is 4; they have Area Attack, so -1 for the defense.
Finally, she flies at Hanami, and tries to grab her with her talons, taking flight with her if she succeed. She rolled a 12, burning 10 Endurance for extra dice. If Hanami succeed in evading, she has to roll against a 6 to determine damage, as the talons graze on her skin (that is, if she tries to physically evade).
Player's turn:
Rolls
Rest of sorcerer's roll: - (5d6)

Aika's initative - (4d6)

PCs initiative - (2d6)
(11) = 2
Lín Jìng / 林静
"You upstart birdbrain! First you claim to snatch Ao-chan, now this?! I will subdue you even if I have to pluck each of your feathers one by one!"
She dismissively makes a mudra of all space being one, teleporting out of the way of the tornado, though her reaction can by no means be called timely. At the destination she is already fully invisible, though this is, once again, too little too late.
Demonic Awakening gives +2 Teleport, +2 Telekinesis, +2 Iron Will, -2 Rude, -2 Arrogant.

Rolls
Defence (Teleport) - (4d6)
(3456) = 18
So that makes the best dice two sixes, for a total of 12 on the defence.
Edit: ugh, I only now realised that the roll against Lín Jìng was the 8, not the 12.
Anyway, waiting for the description of the result before attacking/&c.

(36) - 1 = 8
"A-Aika...!" Eyes wide, she backs up slowly as she watches the grotesque transformation take place. The hand holding her wand trembles slightly. Her fairly substantial means she knows about this monstrous state a yokai can take, but she didn't know one could be forced into it.
What did he do?
She doesn't have much time to wonder about that question before Aika is upon them.
"Damn it...! Get a hold of yourself, chicken nugget!" She yells in vain. She fears there's no way to solve this without bringing Aika down first. However, she shoots a warning glance at Lin Jing. "That man turned her into this, dumbass! So don't go too far, got it!?"
Hanami conjures up a barrier to meet Aika's grab attempt. However, she's picked up, barrier and all. She's just barely keeping the razor sharp talons at bay, sweating as cracks spread across the barrier.

Barrier - (6d6)

She glares at the armored man. "You’re mean."
She tries to shine a beam of light into his visor so Sumeryu can kick his shin or something.

It's your turn! hanami is caught between her talons while she flies around the room.
The sorcerer left in the portal, sorry if that wasn't clear.
"Be nice, bird-girl! Most girls will be carried willingly if you ask nicely!"
She decides it best to force a landing by flying before the harpy and blazing a smoky trail! (How she does this is a fire fairy secret.)
• No Damage (-20)

Then she turns her attention to Aika, or whatever she has become. Someone threatening Doctor Princess. But Sumeryu does not have unthinking fury. She leaps, crossing the room, arms outstretched to grab the tengu-thing in a bear hug and force her to the ground, with Hibana's help.
Flying Dragon Tackle!

Open to Attack since Hibana's giving the setup.
