In a large training ground of nano city, Izuma would be training with Mirko and Yang with the maid blocking a punch from Mirko that made the maid winced lightly.

Mirko: *lowers her fist and took a few steps towards the white hair maid* Come on now, Izuma-Chan.

The blond female would glance to right to see Yang and avoid her knee and counter with her elbow that the star eyed blonde blocking her elbow.

Mirko: *clicked her lips towards the blond* That foresight of yours can be annoying.

Yang would simply grin at this with both blondes jumping back, avoiding a stomp from the maid who would be strike by both females.

Izuma: *would hold her stomach and turn to side, coughing a bit of blood* That's a bit unfair you two. *wipes the blood off her mouth*

The maid would be surprised at Mirko suddenly grabbing her neck and slammed her into the ground, forming a massive crater as Izuma would struggling to pull her off her neck.

Mirko: *stare deep into the maid's eyes* Izuma-chan, you're been hiding something from me. *tilts her head with a smirk* I would appreciate if you show me that old form of your.

The maid would be surprised by this with the blonde letting out a small giggle as Yang tilted her head at this.

Yang: *thoughts while peeking over the hole* Izuma has a form?

The star pupil blondie would jump back from a sudden burst of black energy shooting out of the crater as Mirko would land beside her.

Mirko: *roll her shoulder with a smirk of slight excitement with small stream coming out of her body* There it is.

At the mansion
Zya would be laying on the couch and open one eye at sensing Izuma's sudden power rising.

Zya: *let out a small yawn and mumble to herself* It's been a quite some time since she transforms. *shakes her head with a lazy chuckle* Most be Mirko.

Back at nano city
The black energy soon died with Izuma would hover out of the crater and landed on the ground, her appearance different.

Izuma: *spoke in a cold tone while summoning an odd looking scythe and grab it* I really don't like using this form.

Mirko: *cracked her knuckles and giggle lightly* I can't remember what you call that form. Perhaps you should call black form. *tilts her head* You can name after black-kun after all.

Izuma: *put her scythe on her back and took a few steps forward* obsidian is the form name. Calling that name would be kinda lazy.

She would swing her scythe form, causing both blond females to tilt their body, dodging an arc from the maid.

Yang: *glance behind her and wince slightly at the destruction that was left from the attack* Good thing we are at a training ground.

Her eyes widen and ducking quickly, avoiding having her head cut off.

Izuma: *scoff lightly at this* Mirko was right.  Your off brand sharingan can be annoying.

Yang: *had an a ticked off mark at this and shot a blast that maid deflect into the air* My eyes aren't sharingan!
