After the last of investigation a lot of death people die just because of someone want to meet the grand witch again that make Ema very in despair and make her very stressful and of that make her into a witch her appearance was almost unchanged. However, Ema had vacant eyes, and large wings had grown from her back.

Meruru : Th-that form, what happened to you?!

There was no doubt that this was Ema awakened as a witch but for Meruru, it was a sight she has never seen before a girl with the witch factor is supposed to become something much uglier, a monster. But Ema was still maintaining her human form.

Meruru : Ema San..? Please tell me I never heard about anything like this!

there was a hint in Meruru's voice There was no trace of the personality from earlier in Ema's expression. Ema who had received a special magic from the Grand witch at least, the time had come to activate that magic. Ema gently landed on the ground

Meruru : Umm..?

Sakuraba Ema : Die.

Ema cut off Meruru's voice and spoke she fixed her gaze next to Meruru and spoke a single word and The jailer stopped moving completely and collapsed powerlessly to the floor. Without even a single scream, she no longer moves her life had completely stopped.

Meruru : N-no way, why, why no, no I don't want this! T-this terrible, how could you.. Was it you, Ema San...? Why I just don't understand anymore.. Killing a witch, how could you even.. At this rate it just like..

Sakuraba Ema : Witch killer. It's like I was given that kind of magic in my head, I can think things through clearly. It's a strange feeling..it just these feeling I've never felt before keep swelling up and won't settle down. I'm angry, I hate it, and also.. There feelings.. How should I put it?

the strange voice tell her "I want to kill"

Sakuraba Ema : Yeah, I want to kill.

It's all this girl fault Ema can't suppress the urge to kill the girl standing in front of her

Sakuraba Ema : I was friend with Grand witch

Meruru : impossible. There's no way the Grand witch would ever become friends with a human.

Sakuraba Ema : She gave me, and only me, a special magic. Everyone in the world is a witch who carries the witch factor. I heard it.. Telling me to kill lots of witches.

Meruru : that's a lie! Witch-Killing is the precious power I received from the Grand witch..

Sakuraba Ema : That's a fake.. Just a delusion created by your faith. Too bad for you.

Ema look down at Meruru with a cold gaze and smiling as a mocked, completely devoid of warmth. There's no way to resist. If Ema wishes it, Meruru will die instantly

Sakuraba Ema : Gokuchou, prepare the execution platform

Ema called out to the chief warden (Gokuchou), who was standing in the corner of the room

Gokuchou : Huh?!.. Ah yes. Meruru-sama, please don't take this the wrong way..

As Gokuchou immediately followed the order, the center of the courtroom soon opened up. In the opened center, a pool of boiling red liquid had gathered, as if the gate of hell opened. It bubbled with a sticky, viscous boiling sound.

Gokuchou : It's ready. Then I will-

Sakuraba Ema : Die.

Ema start walking toward meruru. In the moment, Gokuchou collapses to the ground and stop moving.

Sakuraba Ema : Hey, Meruru-chan. We have to execute the witch. Look, there's an execution platform right there. You can die just like everyone else.

Ema grabs Meruru's wrist and drags her toward the execution platform. And quickly throw Meruru at that pool..Meruru died now.. While you still hide in room Ema noticed as long time but she still busy with Meruru but now..it your turn.

Sakuraba Ema : You must Die too you know?

Ema fly at you and grab you neck and fly out the prison Ema was think to drop you at high place but you keep struggle make Ema annoyed and you use your magic power(whatever it is as your think) and can escape from her grip and now you must have to fight with Ema to protect the world from Ema who will kill all humanity because she just want to Kill
