93 Chapter 91 MC vs two devil kings

Boom*

Sona tried to kick my face but I dodged and a big carter formed when she kicked.

"What are you doing? You are in the Student Council." Sona said with little blush. She is now feeling that something big is going to happen.

I smirked then an opera-type theme started to play and they all saw me with flash focused on me.

"Not now…" Sona frowned. Rias too since she could feel that something bad is going to happen. The rest of them become quite interested especially newcomers like Sirzechs, Zeoticus, Baraquiel, and now Serafall. They have heard quite a lot about me and are now feeling curious.

"hmm~

Y is for yummy that's how my food tastes~

U is for the universe, I have traveled so long~

K is for the kiss, any girl wants so long~

I is for interest, some have with me~

O is for one, the only one is me~"

I then vanished. All of them are still in a daze when I appeared right beside Serafall.

"hm hm hm~ My name is Yukio and I would like to say… hello~," I said to Serafall with ice rose in my hand like a gentleman.

She unconsciously took the rose with rosy cheeks. "A-amazing…" She even forgot her magical girl's character when she said that.

Seeing my play, all of them burst out in cheers and start clapping.

"Amazing." Sirzechs praised.

"Yes and the way he appeared here is very interesting." Zeoticus also praised.

"As expected from my son." Mom also clapped then she looked at Serafall then her partner Shuri and both of them nodded with determination. Have to get em all but they have to observe her.

"This cute lovely lady liked my performance? I appreciate~" I said with a bow.

"Umu…" Serafall unconsciously nodded with rosy cheeks hiding her face behind the ice rose that I gave it to her.

"Nee-sama?!" Sona shook her sister who didn't spend even 5 minutes and she is already acting like a maiden in love.

"Ah, yes.. where was I?" Serafall woke up from her stupor and looked at other people.

"You wanted to marry someone handsome called Yukio?" I said.

"Yeah I wanted to ma- wait! It's not it. I wanted to meet you!" Serafall said looking at me.

"Pfff! I can't help but feel quite good after meeting such a cute devil king." I laughed. Seeing in anime and dealing with her personally is a whole different level.

"C-cute m-me?" Serafall blushed with both hands on her cheeks. Everyone's mouth is wide open how strange demon king is acting but the most hilarious reaction is on Sona's face. Kuroka already took out a sofa and some refreshments to enjoy the drama along with mom, Koneko, Akeno, and Shuri. Serafall shook her head. "It's not it! Ahem! I heard you are taking my little Sona away. I can't just allow anyone near my cute Sona-chan. I won't allow it!" Serafall said childishly.

"O-onee-sama stop it!" Sona was deep red. First, her sister appeared in an embarrassing magical girl outfit and now she is acting childishly in front of her love interest being a devil king.

"Aren't you a little late for it? Besides I am her training coach only." I said and shrugged my shoulders. Sona seemed to be a little disappointed but I winked at her and she pushed her glasses with a blush which went noticed by everyone.

"Hah!? Even now you are corrupting my So-tan!" Serafall said.

"I am not corrupting So-chan. I am training So-chan. Look she even improved in that department too." I said pointing at her breasts.

"Stop saying that! and stop saying vulgar things!" Sona said with a flustered face hiding her breasts. She can't help but feel a headache.

"No way…" Serafall can't believe her eyes. She can feel that her sister's body structure has been improved quite a lot.

"And also I am the strongest human on this planet. What qualifications do you have to test my strength?" I said and then the temperature started to turn cold. The aura was coming from two people. Both are devil kings.

Sirzechs also wanted to know just how strong is the person in front of him. Sure he doesn't want to have a bad relationship with me but the said person is mocking a devil king and as fellow devil king he cants just sit around idly and do nothing.

Serafall also glared at me with intimidating eyes. "Ho? I have been hearing this strongest human thing quite a lot and qualifications do I have? I am a devil king and also a big sister of So-tan. I have every qualification to test the said strongest human who is close to my sister." Serafall said now in a serious tone. The atmosphere is now a little tense.

"Hmm? Sirzech-san over there is also devil king. I have meddled with his sister too. He doesn't seem to mind that much." I said pointing at Sirzechs who hurriedly hid the popcorn then composed himself.

But before he could clear something, Rias spoke, "Keep Onii-sama, out of all this." Rias didn't want me to pull any tricks on his brother. She could see her friend's demise and didn't want to suffer the same.

"Whatever! I want to see the strongest human myself. I won't be satisfied until I see you myself." Serafall said pointing at me.

"Ohh, I don't need to even lay a hand to defeat devil king. I can defeat you both anytime you want." I said then the temperature started to feel heavier.

"Yukio-dono, I don't mind being on good terms with you but I still hold the pride of devil king," Sirzechs said coming forward. Serafall also realized that it turned out that fight could happen. She only wanted to test the said human but didn't want to involve Sirzechs in a fight.

"Yukino-san, say something. We don't want a fight." Rias said to mom.

"I guess. I have to…" Mom said with her hand on her cheek. Seeing this, Rias is also ready to stop the fight even if she has to involve herself.

"Buchou, I think you should worry about yourself and Sona President," Issei said pointing at my smirking face.

"Aw, crapbaskets…" Sona has a sweatdrop.

"Is that so? Then ready devil kings. I am going to show you how cunning humans can be!" I said and clapped my hands.

"This is getting interesting." Rias' father said filming this drama along with Shuri and Kuroka.

"Shadow clone technique!" Smore buffed revealing two of me.

"What?" Both Serafall and Sirzechs were stunned seeing unusual magic.

"It's not over yet. Transformation Technique!" Another cloud burst from two of me.

One revealed a girl with a blue dress magical girl with a bob hair cut and glasses. "Hi everyone~ I am a magical girl So-tan! Nice to meet you!☆" Magical girl Sona said with a cute pose.

Both Sitri sisters dropped their jaws on the ground. It didn't end there and MG Sona happily walked and hugged Serafall who was still in a daze. "Onee-chan~ when I saw you, my heart went doki-doki to see my lovely sister! Onee-chan, I love you~ ☆" MG Sona said with rosy cheeks.

"Guahh!" Blood flew from Serafall's nose and she fell on the ground with a happy face. "Guehe... So-tan… loves… me.."

"You!" Sona is now deep red from her frustration. But the drama didn't end at her point.

From another cloud emerged a girl around six years old with crimson hair and a cute face holding a teddy bear. It is Rias in her childhood. She walked innocently towards stunned Sirzechs and original Rias and looked at Sirzechs' eyes with her own puppy eyes.

"O-onii-chan… I will marry onii-chan when I will grow up because Rias loves onii-chan." Little rias said with puppy eyes.

"Guah!" Sirzechs fell on his knees and said with tears in his eyes, "I… admit defeat…" Even Zeotics has tears in his eyes filming little Rias again.

Both of me then become one and laughed, "Hahaha, I told you, didn't I? I could defeat you without even touching you." I looked at both defeated devil kings with amusement. I knew that both of them are siscons and just the right thing to do. Damn me and my acting are top-notch. Someone, please pat my shoulders.

But I didn't get a pat instead I felt two strong energy attacks coming at me.

BOOM

I dodged a water and destruction spell swiftly. "Hey, what was that oyah?" I said then noticed flustered Sona and Rias fuming with anger.

"You!!! How could you make me dress like that in front of everyone?!" Sona yelled with a crimson face.

"And how dare you to say those embarrassing things to onii-sama with my appearance? I won't let you go!" Rias said making another destruction spell raging with anger.

"Calm down. I was just messing with ya know." I said and they halted their attacks. "But it was still hilarious seeing all your faces, hehe." I chuckled.

"You asshole!" Sona and Rias both fired their attacks on me which I swiftly dodged. Sirzechs and Serafall also wake from their dreamland and saw me swiftly dodging their strong attacks. They could also see that both, Sona and Rias, of their attacks have become quite strong and accurate. It's just that I am mastered in dodging.

"Hehe, you can never hit me." I chuckled dodging their attacks with my eyes close.

"Fufufu~" I heard a giggle and saw my mom right in front of me. She spread her dark shiny and long fallen angel wings with her true appearance. "I think you have enough fun for today. But you made girls cry. I can't permit such an indecent act." Mom said pointing at the two behind me. Rias and Sona have tears in their eyes and are not attacking anymore. Crap, but before I could say anything, mom just slapped my head lightly.

BOOOOOOOM

A big storm burst in the room and all of them saw a big carter with me in it after the dust was cleared. All of their jaws dropped on the ground except those who have seen mom's strength.

"Everyone, since my son has caused you this trouble. I, on behalf of my son, would like you all to have dinner with us." Mom said with a cheerful clap.

Serafall and Sirzechs looked at each other and nodded. They don't know whether Yukio is the strongest human or not but Yukino is the strongest mother. Ultimately all of them decided to join the feast since they have heard quite a lot about Yukio's food.

*******

Well, writing Serafall's character is hard since she had bubbly personality when she is with Sona but becomes composed when acting as devil king.
