Oni in Fuuto [Mikan]

Mikan's phone vibrated twice in her pocket, giving off a specific ringtone that only played for one person.
That means it's work, then, she thought, stopping in the street and opening the phone to read the message.

There's only one Dopant but it's not working alone? Mikan took a shortcut between buildings, clipping the W Driver round her waist. Whatever that meant, it wasn't going to be straightforward.
ICE AGE

'Henshin.' A burst of light shone between the buildings as Mikan transformed, running towards the riverside area on foot. If the enemy were uncautious, this would serve to draw some out.

The 'Oni Dopant' bore some superficial similarities to the actual creatures called Oni, but in fact claimed an entirely different origin; its Oni-like powers came entirely from the GaiaMemory- a collection of all the earth's data on those mythical creatures- wielded by a human. Thus, it appeared much as a stereotypical Oni from an old tale, a tall, musculaer, red-skinned humanoid with robes wrapped around its waist. Its face was twisted into the unmoving, snarling visage of an old theatre mask, which worked to conceal the nervousness of the man within the Dopant.
He'd agreed to meet with an individual claiming to be an actual Oni, to act as their intermediary in Fuuto, and in return he'd benefit from their power in keeping his own hide safe.
'How much more are we gonna have to feed that thing, anyway? Grabbing folk's not a problem but if we keep this up we'll have to hide it somewhere else, y'know.'

Emerging further down the waterfront, Mikan didn't take long to spot the Dopant. No normal people looked to be around in the relatively secluded stretch. The problem would be getting close without being spotted... and whatever that thing was it was talking to.
Just by looking, I'd guess that was another Dopant, but... it must be the other party that was mentioned. If getting close would be an issue, then the other option seemed obvious. She held the Raptor Memory in her palm, waiting for a moment to see if an opening presented itself.

'Yeah, yeah, I get it.' The Oni Dopant raised his hands, trying not to seem too intimidated. 'I'm just saying-'

RAPTOR
Having spotted Amaki as she advanced forward, Mikan activated the memory and slotted it into the Driver. Someone else appearing didn't matter; she was still within the area she could cover with her Magnum. Moving into view of the Dopant and others, she raised and braced the Raptor Magnum, pointing it at the obvious group of monsters as one ignited its weapons.
'All of you, freeze. Change back to human form immediately or I'll open fire.' Not knowing where the other Rider had come from or who she was working for, Mikan addressed this to everyone she could see.

[Ah. Whoops >_<]

The Oni Dopant turned to see a gun pointing at him. 'What the- aww, crap. A Memory user!' He hesitated for a moment, before summoning a spiked war club to his hand and charging at the Riders. 'You better back me up!'

Mikan would have preferred to further question the individual who'd just transformed before her, but her priorities lay with the Dopant charging them. It would have to wait.
This could be a setup, but I'll have to assume I can trust her for now. She started snapping off shots at the Dopant, and it twirled its war club like a baton to deflect the condensed balls of ice. It closed the distance quickly, and swung the club wide at the two Riders. Mikan dodged back, Raptor lending her the speed to evade the club, But the power behind it was still a problem.

Now with backup, the Oni Dopant was able to focus its attention on W. Recovering after its club was evaded, it moved back a bit and swung a large sack over its shoulder, opening it out.
Strong winds came out of the bag, throwing Mikan up in the air and making her last couple shots go wild.
It's strong... can't use a Maximum Drive while it's scattering my shots like that... what Memory should I use?
Mikan landed heavily on the ground, losing her breath for a second. She rolled out of the way of another club swing, and switched her Memories back.

With the extra strength she was able to block the next attack, but she still felt the force. The Oni Memory's atack power was obviously high.

Kyoki, as it turned out, was just arriving, pulling his tuning fork free and ringing it against a tree, sending the pitch ringing into what had become a battlefield, signalling his arrival to all six fighters.

Kyoki ran out of the flames, joining the battle in his Oni form. He drew a Rekka into hand, launching a fireball to just above where Mikan was striking in order to assist her. He flipped his other Rekka into hand and ran to join her, watching as the other two peppered their foes with their Reppu weapons.
