The Pure Sister and the Rogue Devil

One Sunday, about a week after I had become a devil and said goodbye to my normal human life.

With no devil work to do, I was enjoying a completely free day.

Here I was, in the park where I had my date with the girl who called herself Yuma Amano, days later I learned from Rias that her real name was Raynare and she was a fallen angel.

It was here that everything began, my life as a human ended, and I was reborn as a devil thanks to Rias.

Even though I was left with a scar that I will never forget, thinking about how I met Rias makes me feel it was truly a blessing in disguise.

As I sat on a bench, lost in thought,

"Ah!"

Suddenly, right in front of me, someone fell dramatically.

"Are you alright?" I said.

I instinctively extended my right hand.

The hand that grasped mine was clear, white, and soft.

"Ah! Th-Thank you."

Her lemon-yellow hair disturbed my heart.

"You're welcome."

"Huh? You understand what I'm saying?" the girl said.

Actually, with the special ability of a devil, foreign languages are automatically translated into my native language.

Therefore, it sounds to me like she is speaking Japanese even though she's speaking a different language.

"Actually, I want to go to a church." The girl said.

If I remember correctly, the only church in this town is the old, dilapidated one on the outskirts, in the mountains.

But what business could she have in such a place?

Just then, a boy running in front of us tripped and fell.

Oh no, it looks like he scraped his knee.

"Oh dear, you're bleeding."

The girl stood in front of the boy and held her palm over his bleeding knee.

Before my eyes, the wound on his knee healed instantly.

'Could this also be a Sacred Gear?' I wondered.

"Brave boys shouldn't cry." She said to the crying boy.

"Thank you, big sister!"

With that, the boy ran off.

"Oh, I haven't introduced myself yet.

My name is Asia Argento." The blonde girl said.

"I'm Issei Hyoudou. You can just call me 'Issei'."

"Alright, Issei-san!"

Asia and I shook hands as we started to get to know each other.

(This was the beginning of my relationship with Asia, who would become one of my precious wives.)

According to Asia, there are three women and one man at that church waiting for her.

"I hope we meet again, Issei-san." She said.

I parted ways with Asia on the road leading to the church.

"Don't do anything reckless."

The next day, when I reported what happened to Rias, she cautioned me.

"As I mentioned before, the three great powers—devils, angels, and fallen angels—are still in a truce." Rias said warning me not to do anything stupid.

There's a risk that even a small incident could start a war again.

"Please understand, Issei." She added.

"I'm sorry, President. It was indeed a rash action."

By the way, I still call Rias 'President' because we haven't made our relationship go public yet.

"President, we've received a request to exterminate a rogue devil," Akeno-san announced as she entered the room.

A rogue devil is one who betrays their master and acts on their own accord. It's a longstanding issue within the devil society.

At 8 PM, our Occult Research Club located the rogue devil hiding in an abandoned factory.

"Rogue devil, Visor! In the name of the Archduke, I sentence you to death!" Rias said.

"Hehehe! I wonder if the blood tonight will be sweet?"

So this is a rogue devil. Visor's upper body retained a human form, but his lower body had eight spider-like legs, making him look like an Arachne.

"Issei, this is a good opportunity to explain the devil pieces. The devil pieces are modeled after chess... Go, Yuuto."

"Yes, President."

With that command, Kiba began to move. He's fast! His speed was incredible, almost invisible to the naked eye.

"The 'Knight' piece excels in speed. Most opponents can't keep up with Yuuto's movements."

"Damn it! Take this, you brat!"

Flustered by Kiba's speed, Visor aimed an attack at Koneko-chan.

"Did you just call me a brat?"

"What?!"

Koneko-chan grabbed Visor's leg and effortlessly flipped him over! 'Where did she get that strength?' I thought.

"Koneko is a 'Rook'. The 'Rook' piece excels in power. Underestimating her because of her appearance will lead to regret."

Flipped over, Visor struggled to right himself and thrashed about helplessly.

"Now, Akeno. It's time for punishment."

"Yes, President. ...Thunder!"

With that incantation, lightning shot from Akeno-san's fingers, striking Visor directly.

"Hehehehe..."

"Hey, is she actually enjoying this?" I said looking at how she was enjoying herself.

"Akeno's piece is the 'Queen'. The 'Queen' piece is versatile, embodying the abilities of the 'Bishop', 'Knight', and 'Rook'. By the way, the 'Bishop' excels in magic... Also, Akeno is quite the sadist."

"Haha, she might be difficult to deal with." I said.

"Don't worry, Issei. As long as you're not an enemy, she's very kind. Akeno, that's enough."

Under Akeno-san's lightning assault, Visor was reduced to a charred mess. Rias stepped forward to the barely alive Visor.

"So, Visor. Do you have any last words?" Rias said.

"...Kill me, please!" Visor pleaded.

"As you wish, I'll obliterate you."

A purple and black magic bullet formed in Rias's right hand and flew towards Visor.

The magic bullet struck Visor, causing him to disappear without a trace.

"This is the 'Power of Destruction' passed down through the Gremory clan." She said explaining her deadly ability. 'I'm glad I am not her enemy' Issei thought for a sec.

"Wow, so this is the president's power. However, "destruction" sounds awfully dangerous." I said.

"Haha… Alright, the mission is complete. Let's call it a day."

"Wait a minute! You haven't explained the 'Pawn' piece yet."

"Oh, right. The 'Pawn' is the lowest rank among the pieces. However, when it reaches the enemy's territory, it can be promoted to a 'Bishop', 'Knight', or 'Rook'."

Therefore, it's like promotion in shogi.

"But I'm ranked the lowest, huh?" I wondered.

"Well, as they say, 'a game of shogi without pawns is a losing game.'" Rias said laughing.

'So, depending on the situation, I can fight skillfully. This piece might suit me after all.' I thought.

"Alright, everyone. Let's do our best again tomorrow." The president said.

"Yes!" everyone answered.

With those words, we disbanded, and I rode my bike home.
