It's morning, and as always, Emi prepares to go to work. She happily puts on her formal suit. As she is combing her hair she notices that she has grown it out to be very she was thinking this she started to remember the times when she was a kid and her father was still around. "Oh, come on! Time to go to work!" she said trying not remember too much or she'll get all flustered and angry and be late for work.

On the way to work, Emi puts on her serious face. It helps her avoid the trouble of a man finding her and them both falling in love. Because, even though she is now living in Japan as a human, she is still half angel and a hero from another world and has a duty to kill someone here, becoming close with someone will only make it hard to say goodbye someday. All of it is just proof that ,one day, she will finish her duty here and return to Ente Island.

"Huft," she sighed deeply while on the train.

The morning train is always crowded and it really gets uncomfortable for Emi. "Eh!" Suddenly, someone's hand starts grabbing her butt. And it takes on a second for emi's face to go from a serious one to a one of anger and fear.

"ugh what bad luck a pervert in the morning!" She thought to herself. Her hands started flying towards that perverts' hands but then suddenly,

-GRIP-

Someone else's hands already smacked the perverts hands away. "What are you doing old man? Do you really wanna be punched by the rest of the passengers on this train?"

The man falls down and begs for mercy. All of the passengers turn to look in the old man's direction. Then, a bunch of men come right away to him and start to yell at him with anger.

"Oh...he's being caught already" said emi while sighing in relieve.

"Thank you for….."

Before she could finish her sentence, Emi turns around and is shocked to see that the one who had helped her is Sadao Maou. And the thing that makes Emi surprised the most is when she sees Maou release his demonic aura and his eyes turn to red. Not only that, he starts to babbling a word like he was on Ente Island as the demon king….

"What a perverted old man! He deserves it! On a beautiful morning like this, how can he do something so indecent to you!" Maou said while grinning full of rage.

Emi doesn't understand why he is like that. But, Maou seems so angry and much more furious than her.

-Psst psst psst-

Once Emi was done staring at Maou she realizes that everyone is looking at them. Because…..because…..well Maou is really….is really starting to look like a causes even more fear further increasing Maous' power. The fear of everyone begins to transfer to him and he starts to transform. But before it happens, Emi decides to take action

-SLAP!-

"Ouch! What are you doing?!"

"You deserve it, stupid Maou!" Emi said

"I just saved you! And in return you slap me in the face?"

"First, I don't need your help! Second, when you help people don't use your demonic aura!" She said with low sound.

Maou realizes what she talked about. Then he tries to calm himself down by taking slow deep breathes and his demonic aura slowly turns back to normal. After that, he is suddenly sulking, "Then next time tell me don't slap my face. Jeez! And you call yourself a Hero? And with that nasty habit of yours, I bet even demons like me don't approve of it!" He said.

"Why is he being so childish about it?" Emi thought to herself with a disgusted feeling

"I don't care about what demons think about me! the main thing is that if you help people, especially me, don't use your demonic aura like earlier!" Emi said

"ok fine"Maou said.

"huft! But anyways I appreciate your help, even though I don't need it in the first place." Emi said, saying the first part a little quietly

"Yeah yeah, but did it ever occur to you that if you were the one to take down the old man earlier, you would become target of his because you embarrassed him? It would end up causing more trouble for everyone." replied Maou with a serious face.

"Why do you worry that much? I don't need your concern Maou! I can take care myself better." said emi angrily.

"If you can, then it would have been for the best if I didn't save you when you were being played with by that perverted archangel! Ah, that whole time I was thinking to help Chiho, not you, so you can count it as my devilish trouble for you." said Maou grinning.

Emi became more furious. She really wanted to draw her sacred sword, right there, right now, and kill him. But before she intended to do it her phone suddenly rings.

It looks suspicious because the caller id is withheld but nonetheless Emi decides to pick it up.

"Yes?" Emi said.

"oh, it's you. Why don't you use your cellphone to call me? I thought it was urushihara." hearing emi say that makes Maou secretly feel curious.

"What? What's the matter?"

"Wha-"

Suddenly emi's face turns pale. She is quiet for awhile with a shocked expression. Maou starts to worry seeing her like that.

"Yes, Yes, I understand. I will call you later."

Emi shut her phone with her hand shaking. She is acting like a person hearing really….really bad news.

"Hey, Emi?" Maou tries to talk to her but she is in deep thought.

"EMI!" Maou yells

"What!" emi is shocked with Maou screaming right in her ear.

"What happened? Suddenly you are being quiet, it creeps me out" Maou said with worried expression.

"Nothing, I just….. was thinking about something…hahaha" Emi said making Maou even more curious.

"Hmm, Really?"

The train arrives at the station. Emi and Maou walk out without talking to each other.

"Then, see you later" Emi said before suddenly running away.

"That isn't like her. Usually she will start fighting and bad mouthing me before she leaves. something is wrong with her and I'm going to find out" Maou thought to himself.
