Somewhere else,
Rika's luxurious apartment,
Morning...

Rika's POV

I stood at the balcony quietly, enjoying the cold morning breeze by myself. I tucked a strand of my hair behind my ear as my mind wandered somewhere else. I couldn't stop thinking about my recent patient... Izuku Midoriya.

One of Pops'
grandchildren...

If only I have much more authority than that stupidhead yakuza leader...

I would have taken custody of the two girls from the beginning.

Ever since Pops fell into a comatose state, I couldn't stop worrying about the two girls' future.

I couldn't trust Overhaul to take care of them... And now look what happen to them.

That little girl, Eri, is used as the crux of his plan. Izuku-san is locked inside her own room like a prisoner.

I should have taken action earlier. I really regret not taking them in.

Heaving a deep sigh of relief, I sipped on the warm coffee. I looked up to the blue sky, my eyes narrowing in seriousness.

But that is not the thing I worried the most.

What concern me is..

Izuku-san's face showed up in my mind. Her innocent bright smile flashed before my eyes, and I accidentally gripped my cup.

... Izuku-san's frightening Quirk!

My mind recalled the scenario of the check up yesterday...

~~~~~

Morning,
Izuku's room,
Shie Hassaikai hideout...

I was still running a check up on Izuku-san, checking for any sign of sickness. Overall, she was healthy. Very healthy. The only thing left to be checked was...

... Her Quirk.

I was a doctor and a Quirk expert. My Quirk was called "Analyze". By touching my target directly , I could analyze their whole body to find out about their personal information and Quirk.

By personal information, I meant by every single information about my target. Height, weight, their likes and dislikes, age, name... Even their house address. And of course, their Quirk information too.
I Analyzed Izuku-san's body once again, but everytime I did that, my Quirk was cancelled. I shifted my gaze to my patient. She seemed confused.

" Izuku-san... Can you deactivate your Quirk? If this continues, I can't figure out your Quirk." I said softly to her. A gasp of surprise escaped her mouth.
"B-but I didn't activate my Quirk..."

Really? Weird..

"Well, maybe you forgot that you had activated it before I arrived. Alright, now deactivate it."

"Um, okay..."

Izuku-san closed her eyes, focusing on to cancel her Quirk. But all of a sudden, her eyebrows furrowed in pain.

"Izuku-san, what is wrong—"

"ARGH!"

Izuku-san screamed in agony, which scared me. She dropped on her knees while gripping the collar of her oversized shirt. I immediately knelt down to help her.

"Izuku-san, calm down! Take a deep breath... Don't panic." I told her calmly.

I reached out my hand to comfort her, but she suddenly gripped my wrist. Her grip wasn't weak. It was very firm, that I started to feel hurt.

Izuku-san slowly lifted her head up, her piercing blood red irises glared into mine. I could feel chills all over my body when I saw the intense gaze.

Hold on, I thought her eyes' colour is green! How in the world—

“...ł₣ ɎØɄ ⱤɆ₳ⱠⱠɎ ₩₳₦₮ ₮Ø ₣ł₲ɄⱤɆ ØɄ₮ ₮ⱧɆ QɄłⱤ₭... ɎØɄ ₥Ʉ₴₮ ₴₩Ɇ₳Ɽ Ø₦ ɎØɄⱤ Ⱡł₣Ɇ... ₮Ⱨ₳₮ ɎØɄ ₩łⱠⱠ ₦ɆVɆⱤ ₮ɆⱠⱠ ₮Ⱨ₳₮ Ɏ₳₭ɄⱫ₳ ⱠɆ₳ĐɆⱤ ฿₳₴₮₳ⱤĐ...”

Izuku-san warned me, her voice was really husky and deep, yet still maintained the feminine tone. Her hair began levitating slightly in the air. Out of fear, I nodded my head non-stop.

"I swear on my life, I won't tell Overha—

“ĐØ₦'₮ ɎØɄ Đ₳ⱤɆ ₮Ø ₴₳Ɏ Ⱨł₴ ₦₳₥Ɇ ł₦ ₣ⱤØ₦₮ Ø₣ ₥Ɇ!”

I was on the verge of passing out from fear. Is this really Izuku-san?

" I-I swear on my life... I won't tell that man about your Quirk, Izuku-san..."

Izuku-san stared at me silently before she released my wrist. God, she left a bright red mark around my wrist.

Her hair stopped floating in the air and her eyes returned to their original colour; emerald green.

Izuku-san looked like she just woke up from sleep. She looked at me in perplexity.

"Rika-san, are you okay?! What happened?!"

Regaining her sense, she held my shoulders worriedly. I was still shocked from what happened earlier.

What... In the world is
that..?

"Nothing... I'm fine. let's continue the check up."

I seated her back in her bed,holding out my palm close to her face. A screen -- that only me could see -- displaying various information about Izuku-san appeared before me. I read the informations carefully, especially the Quirk part...

Most of the time, I could even read the personal information about my patients... That them themselves never know.

My eyes widened in extreme shock when I read about her Quirk.

Quirk Information

Name : Nullification

Ability : Able to completely repel Quirk, which make her invincible toward any Quirk.

Effect to enemies : the enemies' Quirks will be forcefully deactivated by Nullification if they are in the range of the Quirk user. They will also feel hot if they are exposed to this Quirk for too long.

Weakness : Vulnerable to physical attack that isn't caused by Quirk.

Side effect : If this Quirk is used beyond its limit, the user's body will start feeling hot, as if their blood is boiling inside their body. Soon, they will pass out from exhaustion.

So that is her Quirk! She can repel Quirks! No wonder my power didn't work out on her just now.

My eyes kept reading the information about her Quirk. My gaze stopped after I reached the "Additional Information" part...

And at that moment, my heart dropped.

I had frozen in fear mixed with astonishment.

... Is this why "Izuku-san" warned me not to tell Overhaul?

This special ability of hers... Is very dangerous!

There was even a warning about her Quirk. Wait, warning? For as long as I have worked as Quirk doctor, analyzing many people's Quirks, I have never seen a warning about a Quirk before.

.... I have a bad feeling about this...

I gulped down my saliva and read the warning.

ⱧɄⱤ₮ ⱧɆⱤ,
ɎØɄ ĐłɆ.

WHAT THE HELL—

What in the world is this warning?! It makes no sense—

The screen suddenly disappeared from my sight. I was surprised.

“ɎØɄ Ⱨ₳VɆ ₴ɆɆ₦ Ɇ₦ØɄ₲Ⱨ, ĐØ₵₮ØⱤ
Ɽł₭₳... ₦Ø₩...”

“₮ɆⱠⱠ ⱧɆⱤ ɆVɆⱤɎ₮Ⱨł₦₲ ɎØɄ ₭₦Ɇ₩, ɆӾ₵Ɇ₱₮ ₳฿ØɄ₮ ₥Ɇ... ₲Ø₮ ł₮?”

"Y-yes! I promise!"

Izuku-san returned to her original self. "Huh? What happen...?"

I was baffled. I was confused. I was at loss.

Why did that "Izuku-san" has to come out without warning first?! She almost gave me a heart attack!

I don't want to believe it but... Perhaps, Izuku-san's Quirk...

"Rika-san, how is it? What did you find out about my Quirk?"

"H-huh? Well..."

Thinking can come later. I should explain everything to my patient first.

And as "Izuku-san" warned, I only told her the necessary part, and kept the others as secret...

~~~~~

(Flashback end)

Back to present...

That girl...

Who talked to me in such a threatening way...

I don't want to believe it at all...

The theory that popped up in my mind...

I have seen this type of this Quirks before, but not this dangerous... Or sentient.

Probably, that girl who talked to me... The one who took control of her body without she realized...

...is Izuku-san's Quirk!
