Thump, thump, thump!
Rem's eyes grew wider and wider.
She felt her heartbeat quicken, her body undergoing drastic changes.
Especially the itching on her back and at the base of her tailbone, which was unbearable.
"Sister, what is this..."
She bit her lip tightly. "It feels like something is about to..."
Ram quickly said, "It should be wings and a tail. Don't hold back, just go with the feeling."
"Mm."
Rem nodded and let them grow.
Whoosh!
The skin on her back writhed.
The next instant.
A pair of black wings burst out like a butterfly from a cocoon.
Her tail, with a heart-shaped tip, also quickly emerged, swaying back and forth in front of Ram, occasionally poking her in the face.
"Rem, is your tail itchy?"
Ram said expressionlessly. "Then let me help you."
After saying that, she grabbed the tail and began to knead it fiercely.
"Hiss."
Rem stumbled, bracing her hands against the wall. The outer clothes she was holding slipped.
Two curves, losing their cover, immediately bounced a few times.
Glare!
Ram's face stiffened, her gaze fixed intently on Rem's chest.
Damn it.
Even though they were twins...
The gap seemed quite large.
She looked down at herself and immediately became depressed.
What was going on?
They ate the same things.
Why was it like this?
"Sister, stop messing around."
Rem glared at her older sister with shame and anger, quickly pulling her tail back.
"Tsk, tsk. Unexpectedly well-endowed?"
Ayato looked and smiled faintly.
"Th-this..."
Rem's face instantly flushed bright red. She quickly grabbed her outer clothes and put them back on quickly.
In a moment.
She was completely red-faced.
Ayato glanced at her and didn't tease her further.
He was afraid the child might faint.
Then!
Ayato raised the Boosted Gear and began to bestow the Balance Breaker.
Hum!
A crimson light slowly drilled into Rem's body.
"Hmm?"
A new power made Rem's body tremble slightly.
Then!
She only felt that inside her body, earth-shattering changes had begun.
As if this power responded to her deepest desires.
The next moment!
Crimson armor began to gradually cover Rem's entire body.
My power?
Rem's eyes widened, a flash of excitement in them.
Compared to when she was just an Oni...
The improvement in power now was simply unbelievable.
Indeed.
Becoming Master's servant was the most correct choice she had ever made.
Just as Rem was getting excited, Ayato was also slightly surprised.
He didn't expect...
Rem had also awakened her Balance Breaker in such a short time.
Even though...
Her older sister Ram had better aptitude.
"Or... is it because of emotions?"
Ayato stroked his chin, a thoughtful look on his face.
It seemed... not impossible.
But regardless, it was a good thing.
No one knew how long passed.
Rem's entire body was now covered in a layer of delicate red armor.
Her Devil Wings were even covered by red light wings.
Her Balance Breaker was strikingly a Reinforcement type, most suitable for close combat.
"My power..."
Rem clenched her fist, her expression gradually becoming excited.
Powerful!
Power she couldn't have imagined before.
This was strength she never could have dreamed of having before.
Having just become a servant, she already possessed such power.
And in the future...
She would certainly become even stronger.
Because she could feel that some restriction that had long limited her had been completely broken.
And all of this...
Came entirely from Master.
How... could she repay Master?
Unconsciously...
Her mind echoed with the sounds from last night.
Master seemed to really like such things.
Thinking about it, her face grew even redder.
Although she was shy...
It was all to repay Master.
She looked up, just about to speak, when she saw the crimson eyes right in front of her face.
"After the Balance Breaker comes the Blessing."
Blessing?
Rem blinked.
Her older sister hadn't mentioned this either.
"Mmph..."
The next moment, her eyes widened.
Her skin gradually flushed pink.
So this was the Blessing. It felt like an even vaster power surging into her body.
A moment later.
Ayato released Rem and was about to step back.
But he found his arm tightly grasped.
Rem lowered her head and said shyly, "Master, thank you for making me a Devil, for giving me the power to take revenge."
"Rem hopes..."
Her voice grew softer and softer.
But Ayato heard clearly.
To this.
A smile appeared at the corner of Ayato's mouth.
Faced with his servant's resolve...
He naturally had no reason to refuse.
The next moment.
A magic circle flashed.
Ram: "???"
