[A slight shift on his stance gets Mamoru to scan his surroundings and spot the kid who scrambled behind him. While in the last time they fought Mamoru could assess an excellent physical condition and some magical skills that need finessing, the fact that Atsumu is now holding a sword makes it plenty more easy for him to pinpoint his good and bad points.

Though he still asks, because he's an ass.] You know how to use that thing?

[He means the sword and the knife, and honestly, Mamoru should really request the strap of throwing knives he tends to carry under his jacket. Note to self.]

I'm not sure. But widen that stance of yours. Its chicks are coming.

[And indeed, three creatures approach, surprisingly fast for the way their entrails are just there, swinging with each step.

Step and not prowl. A lot in these beings is uncannily human, especially in the limbs, which means they have the same tendons.] Stay put.

[Sorry for barking things around, Atsumu, but Mamoru needs to test something. He lunges. The gravitational axis of these creatures is all wrong, teeth and claws first, but if he gets past the length of their arms, the rest of them can't injure them, and if he ducks enough—

He slices through the back of its heels, and the being at the forefront of the trio screeches and scrambles and falls faces-first on the floor, its legs contorting underneath the layer of skin from the tendon coiling unnaturally around muscle fibers and bone now that it wasn't anchored.

'Hello, Achilles.'] Kill it! I'll take down the other two.
