Infinity 🌙✨ Shoto + female reader

I will never leave your side

(Time skip to when Shoto and Kiwa are both 12 years old)

Kiwa's pov:

Ugh! Another morning 

Another day of tough training, again with that flame god.

Lately, I developed a new quirk by my own, and I think it is about stars in the sky.

I can shape the stars in any shape or forms I want to, and I can make them as a shield to protect myself, how cool is that?

This quirk is a combination from both of the sun and moon, I'm pretty proud of it, as you all know, my oni san already came up with his quirk, Chikusa nee san too! They are both really strong. Aira nee san didn't have a quirk came up by her own, but as she has super strength, which I'm really impressed with. She is our super woman in the squad, and everyone looks up at her.

Back to now, I'm just a 12 year old who is mindlessly training to become a pro hero, I just think , I'm very useless, compared to my siblings.

I can't even win my father in any spars.

The door of the training room was suddenly slammed open, what the- it's my father again?

Unfortunately, I'm right.

'KIWA, it's the time to spar again! Get ready.' His loud voice boomed though the hallway.

Uh oh, I have a very bad feeling about that.

Oto san shot his flames towards me, causing me to do a back flip, dodging the attack.

'Not too shabby.' He smirked, while pounding a flame ball in my face.

No one's pov:

The flame god pounded a huge flaming ball in Kiwa's face.

'Galaxy, first form, Star shield!'

Luckily, Kiwa is fast enough to use her shield to block that shot.

'Hah, not bad, let's see if you can block this.' He laughed.

What do he think he is doing?

He made the whole place like it's on fire, and- wait what?!

Kiwa stood there dumbfounded, she don't even know how to react.

He used his last form on Kiwa.

'Moon, slash. Crescent blades!'

Too late...

The flames whooshes to her side in a spilt of second, making her whole body burnt  since she isn't fast enough to react to the sudden attack. She knows thing are not going to be good when she knows she was been burnt by her father's flames.

'Too slow!' Asahi bellowed, not noticing his daughter was injured.

'What-the hell-?!'  Was Kiwa's last words before she became unconscious.

Chikusa's pov:

I was peacefully reading in my room with Aira when...

All of a sudden, I have a bad feeling, but why?

I smell- smoke in the training room?!

'Aira! Head to the training room, now!' I yelled at the top of my lungs.

'Wait, what happened?' I heard Aira turning towards me.

'The training room is on fire, and- Kiwa is inside there!' I stood up and ran to the training room as fast as I can, with Aira following behind me.
