A Certain Magical Index: My Reincarnated Girlfriend(s)

A Gemstone...

As the name suggests, is a natural, unpolished mineral crystal.

So, unlike artificial ability users, the Gemstone Espers are naturally born with their abilities.

The abilities of a Gemstone are instinctive, allowing them to use their powers freely without any calculations.

Honestly, even now, Kiryu still does not feel quite real about being a Gemstone ability user.

After all, he can't generate electricity, control fire, manipulate wind and rain, or perform vector manipulation... those more noticeable abilities. Being good at learning... how could such an ability be a Gemstone? He's never seen such a ridiculous superpower.

Infact, who's to say that it's not just plain intelligence?

But even if it is a useless ability, he still wants to know what level his Gemstone ability is.

Sogiita Gunha is the world's greatest Gemstone, a natural Level 5 ability user.

His inexplicable superpower is quite enviable, and honestly, Kiryu kind of wants it. But he's not greedy; if he has it, he has it, if not, it's no big deal. Does lacking an ability mean he can't live?

"This is my testing point..." Kiryu stood outside a pure white research institute.

Of course, he wasn't alone.

Kihara Enshuu was holding his hand, guiding him. Otherwise, Kiryu would have gotten lost long ago.

"Don't worry Onii-sama, no matter what your ability is, you're the best in my heart!" Enshuu comforted him, seeing Kiryu's complex expression and thinking he was worried about his ability level, she quickly patted her chest to assure him.

Kiryu being a Gemstone ability user was something Enshuu had already learned from him.

This made Enshuu very happy, as it meant her Onii-sama wouldn't become a research subject for others.

Her Onii-sama's body... only she could touch it!

If research was needed, it should be her doing it!

Thinking about the times she had seen her Onii-sama's body, Enshuu's eyes overflowed with affection...

It was more fascinating than any science she had ever studied!

Of course, Kiryu had not told her the truth about his ridiculous ability to learn quickly. He only told her he was a rare Gemstone ability user. Seeing her so happy for him, he couldn't bring himself to tell the truth.

"Enshuu-chan!" Kiryu struck a Shinbo 45-degree angle pose, looking at Enshuu.

He had studied the technique carefully.

1. Raise the chin upwards, the body can lean back to varying degrees.

2. Turn the face slightly to the side.

3. Gaze meaningfully downwards.

Since Enshuu was petite, this pose was just right.

"Actually, I was thinking, since I'm already so handsome, if my ability were too powerful, how would others live? So I think my ability shouldn't be too strong, just normal and average, so others can have a chance."

Enshuu nodded in agreement, "You're absolutely right Onii-sama! But no matter how low-key you are, you can't hide your brilliant and noble character and heroic soul! A gem will always shine when it's time to shine!"

Holding the Shinbo 45-degree angle pose for too long made Kiryu's neck sore. He quickly covered his neck with his hand, feeling a bit embarrassed by Enshuu's unwavering admiration, and said, "Enshuu-chan, let's keep these words between us, okay?"

"Yes, I understand! As long as I know how great you are, that's enough!" Enshuu agreed.

"As long as you understand." Said Kiryu.

One was extremely narcissistic, the other a blind worshiper... A perfect combination indeed!!

So, amidst their incredibly awkward conversation, someone finally came out of the research institute.

It was a researcher in a white lab coat, a man in his thirties or forties.

"Are you Mr. Nanaya? As per the directive of the Board of Directors, we have prepared the testing process for you."

Seeing someone come out, Kiryu stopped boasting to Enshuu.

He had to admit, boasting to the young loli felt amazing!

Seeing her unwavering belief and admiration for him, Kiryu felt energized...
