Beast Gacha System: All Mine

August Dawnoro had been informed that his son brought his step-daughter home because she felt unwell. 𝑓𝘳𝘦𝑒𝑤𝑒𝘣𝘯ℴ𝘷𝘦𝓁.𝑐𝑜𝑚

It hadn’t seemed like a big deal at first. Sienna’s participation in the conference wasn’t for any major role. Just attendance, observation, the kind of exposure that looked good on records but didn’t carry real weight. A great opportunity for a young girl, an experience to broaden her horizons.

Nothing to worry about.

He finished his work for the day, reports, correspondence, the endless machinery of running a house that answered to no one but itself, and learned that Sienna had woken. He made his way to her room, as was his habit when any of his children were unwell, and found a scene that stopped him cold.

Sienna was crying.

The last time he saw her cry was when she was still a little girl who had scraped her knee. This was different. This was real crying, the kind that shook her whole body, that left her gasping for breath, that she pressed into her mother’s arms as if trying to hide from the world itself.

Ines held her, murmuring soothing sounds, but her eyes when she looked up at August held the same confusion he felt.

"What happened?" He kept his voice soft, gentle. The voice he used with children.

Sienna wouldn’t speak. Just shook her head, pressed deeper into her mother’s embrace.

But when she finally did speak, when Ines managed to coax the words out of her, it was a single name.

Cecilia Araceli.

The anger in his daughter’s eyes.

The hatred.

August had never seen that expression on Sienna’s face. Never. She was such a sweet girl, always smiling, always eager to please. To see her make that face...

Something shifted in his chest.

He wasn’t close to Sienna. Not truly. He had always been honest about that, with himself, with her, with Ines. But he had tried. Always tried. He had made the Dawnoro her home, had given her his name, had welcomed her into his family as if she were his own blood.

When she had finally accepted Dawnoro as her surname, something had soothed inside him. A piece of guilt, perhaps. A sense that he had done right by this girl who deserved nothing less than a father’s love.

He had married Ines with an agreement. Clear terms, honestly stated. She would have the authority and title of the lady of the house, but they would not conceive a child together. Arkai was his one and only heir, a promise he had made to his late first wife, Belinda, and a promise he would never break.

He always felt he owed something to Ines. To her daughter. He couldn’t treat them equally, not in the ways that mattered most to a house like the Dawnoros. But the best he could give was respect. Love. Attention.

So seeing Sienna, his Sienna, the little girl he had raised as his own, scowled with tears streaming down her face, hatred burning in her young eyes...

He was mad.

Who had done this to her? What had done this?

The moment she gave him a name, he began investigating.

Cecilia Araceli.

A student. Just a student. A commoner orphan, raised in a clinic, discovered to have unique magical talent and enrolled in the Athenaeum on full scholarship.

This lowly girl was causing all this?

August contacted his son in the morning. The response came not from Arkai, but from Roarke, his right-hand man, his shadow, his voice when he couldn’t speak himself. Arkai was on his way to the conference. As Student Council President, he needed to be present, to host, to represent.

August decided not to bother him further.

But he dug deeper.

And quickly, more emerged.

Best friend of the empire’s princess. Entangled with the son of the Edengold Family. Entangled with a mysterious transfer student who had beaten Arzhen Vasiliev to a pulp.

She screamed trouble.

But at the same time, she was also famous. Famous for her competence. Her record-breaking exam scores. Her last magic initiation, completed remotely while simultaneously acing her finals.

Perhaps... just perhaps, she was a dangerous individual. Someone who might threaten his daughter. Bully her. Hurt her.

Then one more detail surfaced.

A "prank", at least, that was how it had been officially recorded, had trapped both Cecilia and Arkai in the student council office a few days before the conference.

August could smell trouble when he saw it. This detail alone wasn’t enough for action, wasn’t enough for worry, but it added to the picture. To the sense that something was off about this girl.

He wanted her in his office that morning.

Simple enough. He could care less that she was part of the conference committee. Who would refuse him? What would happen, anyway? She was just one of dozens of committee members, not even the leader. A simple request, a simple appearance, a simple conversation.

But the Headmaster himself refused.

Interesting.

Lazuardi was blocking him. Protecting her.

He sent a second call. And this time, despite the Headmaster’s protection, the girl herself agreed to come.

Ha.

Arrogance.

August leaned back in his chair, staring at the response, and allowed himself a small, cold smile.

But when she arrived, it was just an ordinary, beautiful young woman with a warm smile.

August studied her as she stepped into his office, cataloguing details with the practiced eye of a man who had spent decades reading people. Blonde hair. Sea-glass eyes. The kind of face that belonged in temples stained glass arts. Serene, composed, almost holy in its stillness.

Nothing special or threatening. Just a girl.

Though something was weird.

His son stood there with her.

Frowning.

"Father." Arkai’s voice was controlled, but the edge beneath it was unmistakable. "What is the meaning of this?"

The feeling of trouble returned, settling into August’s chest. He met his son’s gaze and held it.

"And what is the meaning of this, son?"

He rose from his seat behind the massive oak desk, the movement unhurried.

"I simply called Miss Araceli to come. Why are you following her all the way here?"

"Miss Araceli is injured." Arkai’s voice didn’t waver. "And you forced her to come all the way here. Of course I would come with her."

Talking back?

That was rare.

His son had rarely gone against him in any situation. Arkai was obedient, respectful, correct in all the ways a heir should be. He understood his place, his duties, the weight of the name he carried.

Could it be... for her? Had his son also become entangled with this girl?

"Injured?" August’s eyebrow rose. He turned his attention to Cecilia, letting his gaze sweep over her once more. "I beg your pardon, Miss. I didn’t know you were injured from the prank. Of being locked together with my son a few days ago, I assume?"

Arkai’s eyes faltered.

Just for a moment, a flicker of something August couldn’t quite read. His father had found out about that day. But perhaps August didn’t yet know about what had happened at the conference hall today.

But before August could pursue that thread—

Cecilia giggled.

The sound was sweet. Light. Completely at odds with the tension crackling through the room.

She had no fear at all.

"It’s a pleasure to finally meet you, Lord August Dawnoro."

She curtsied. The gesture that acknowledged his position without diminishing her own.

Then she raised her face, those sea-glass eyes meeting his without a flicker of hesitation.

"You can call me Cecilia."
