Author here! Just to let you know Izuku's quirk is revolves around a dragon type of quirk. It works a bit more differently than what you would expect so....

Hope you enjoy!

Itsuka woke up from her good little nap. She looked around while still trying to adjust her eyes, she is in a guest room.

She remembers a bit from earlier when Izuku had complimented her. She had a tint of pink but shook it off.

She got up and stretched a bit before walking out of the guest room.

She walks to the living room where Izuku was just lifting weights...without no shirt.

Izuku: 96...97...98...99...100!

He puts down the weights and drys all the sweat from his body. Not noticing that Itsuka was right there.

Itsuka was having a hard time trying not to blush while her ears had steam coming out of them.

Itsuka: U-uh Izuku?

Izuku slowly turns around with a bit of hesitation...

Izuku: I-Itsuka-chan?!

Itsuka: I-I was wondering if... You know... Maybe we could train together...?

Izuku: Sure! Let me go take a shower first!

While Izuku was taking a shower, Itsuka was packing a few sandwiches for when they get hungry.

Itsuka: Hurry up Izuku-kun! The faster we get there, the faster I can train my quirk!

She says while she opens the bathrooms door...

Izuku: Chotte Matte! Don't open the doo-

Itsuka:....Baka Hentai!

*Little Timeskip*

We can now see Izuku with a bump on his head with a few bandages on his cheeks.

Izuku: I told you not to open the door.

Itsuka: Baka! I didn't think you would take that long in the shower!

Izuku: You could have knocked on the door first...

Itsuka: Well when you put it that way... It might be my fault...

After a bit of walking they made it to Kendo's Dojo.

Itsuka: Okaa-san! I'm home with Izuku-kun!

Elizabeth: Ah! Itsu-chan and Icchan!

Izuku: Hey Mrs.Kendo!

Elizabeth: What are you two doing now?

Itsuka: We were gonna practice our moves and to see which type of fighting style fits us best!

Izuku: I want to have a style where I can have speed and power.

Itsuka: While I want to have a style of power and defense!

Elizabeth thought for a moment...

Elizabeth: Hmm... Izuku could use taekwondo. And for you dear it would have to be karate and jiu jitsu.

Itsuka/Izuku: I'll give it a try!

*Mini Timeskip BTYB a Chibi Itsuka having hearts coming off of her*

Izuku: Jeez... Just how long will it take to perfect this style Itsuka?

Itsuka: Most likely two to three weeks...

She says while she wipes the sweat off of her body.

Itsuka: How about a lunch break?

Izuku: I could go for that.

He takes off his added weight and stretches. Itsuka leaves and goes to the kitchen where she left a basket of sandwiches.

She walks back into the dojo and sees Izuku gripping his hand while his power was surging through his veins.

He flipped in the air while a streak of green lightning follows him. He also grew scales that seemed to be green with black tips.

The only word that Itsuka could make out was-

"Stunning"

Izuku hears the word and immediately stops and falls with wings coming off his back. He lands while his wings retract back.

Izuku: U-uh... What do you think of my power?

Itsuka: Stunning like I said. Although I'm wondering why is there wings on your back...

Izuku: Long story... I'll tell you when we eat.

Itsuka: You better!

Itsuka hands him a turkey sandwich.

Izuku: Well here I go...

*Flashback 5 years ago*

Izuku: Okaa-san!!!

Inko: Yes Icchan?

Izuku: Can you please help me?! Somethings itching my back...

Inko: Sure dear. I'll be right there.

She goes into his room and sees Izuku vigorously scratching his back.

Inko: Dear what are you doing?

Izuku: It itchs! My back feels like there is nails stabbing into me!

She quickly responds by inspecting his back only to see little wings that are seemingly attached to his back.

Inko: D-dear... You might be surprised but... You have wings now.

Izuku: Nani?! I have wings now!?

*Flashback End*

Itsuka: Huh.. So why didn't you tell me sooner?

She said while softly hitting his back.

Izuku: Haha! Well the downside to this is that I can't ride in anything for more than 30 mins or I'll become sick and nauseous.

Itsuka: Oh my god! For such a good quirk to have that kind of drawback is hilarious!

She laughed.

Izuku: Right...

Author here! I'll slowly reveal his quirk here and there! So look out! Bye!
