The first class ended quickly. Rebecca couldn’t care less about what the Blood Clan woman up front was saying. Throughout the lesson, Lorin’s flirtatious glances at Rebecca went completely unnoticed. Instead, the boy sitting beside her got distracted. He thought to himself, “The teacher is batting her eyelashes at me—she must like me!”

“Uh… Rebecca… I mean… Big Sister! Boss!!” After class, Glendon ran over, his face flushed with excitement.

Rebecca frowned and closed her book.

Glendon saw her movement, his eyes fixed on the book in her hand. Instinctively, he took a step back. In his mind, whenever Rebecca reached for that book, it meant she was about to hit someone.

But Rebecca ignored Glendon completely. She simply swapped to another book and kept reading.

“Uh… um… would you be my boss?” Glendon asked cautiously.

At that moment, Rebecca finally reacted. She looked up and gave him a glance.

“Are you royalty?”

“Well… sort of…” Glendon scratched the back of his head, embarrassed. He was only a distant royal relative—not of the royal surname.

“Then… can you… help me find books on Demon Potions in the royal archives?” Rebecca asked.

“Demon Potions? Sure! Of course!” Glendon paused briefly, then eagerly agreed. Though he was a princess’s child with little real power, he still had hidden privileges—like access to the royal library, off-limits to ordinary people.

“Good. From today on… you’re my underling…” Rebecca said, then turned away.

Glendon’s heart leaped. His face lit up as he exclaimed, “Boss!!”

Rebecca waved her hand, signaling him to leave.

Glendon grinned and ran off happily. Rebecca glanced at him laughing with his friends and found it oddly amusing. Children’s world was so simple, free of deceit. Though they’d been enemies before, things turned dramatic when Rebecca beat up bullies bothering Glendon just because she found the noise annoying. Now, he’d let go of their past conflicts. Being around these kids was truly relaxing.

“R-Rebecca… uh… Teacher Lorin wants you in her office…” A classmate suddenly ran over and said.

Rebecca was taken aback. She thought, “What does that guy want now?”

Though grumbling inwardly, she knew she had to follow academy rules. After all, that person was her teacher now. Ugh, how annoying. Why did she have to meet such a clingy person?

Led by the classmate, Rebecca arrived at Lorin’s office. The classmate, seemingly terrified of Rebecca’s “violent tendencies,” dropped her off and dashed away.

Rebecca pursed her lips and knocked.

“Come in~” Lorin’s voice came from inside, trying to sound composed but brimming with excitement. Rebecca’s scent was utterly intoxicating; she’d sensed her approach from afar.

Rebecca entered and found a private office. Clearly, Lorin’s treatment was better than Professor Monis’s. After all, Monis worked in a shared office.

Upon seeing Rebecca, Lorin’s face lit up with barely contained joy. She hurried to the door, shut it, and knelt before Rebecca.

“Master~ Master~ Master~~~~”

“You’re quite impressive… infiltrating Hobi Academy…” Rebecca knew the Blood Clan loved mingling with other races. They were masters of concealment, adored luxury, and thrived in human society—as long as they weren’t discovered.

“Hehehe~ For you, Master, what’s this worth?” Lorin hugged Rebecca’s leg, rubbing her head against her stomach.

This time, Rebecca didn’t push her away. She stared thoughtfully.

Rebecca patted Lorin’s cheek. Lorin looked up, curious, waiting for her command.

“Staying by my side is fine… but… what can you do?”

“I can be your puppy, Master~ Woof! Woof woof~~” Lorin shamelessly barked, even sticking out her tongue and panting.

“…” Rebecca facepalmed. She hadn’t expected Lorin to have zero limits. What she didn’t know was that Lorin sensed she was a high-ranking Demon Race member. For a Blood Clan, missing this chance to pledge loyalty would be foolish. Dignity? Not that important.

“Actually, I prefer cats…” Rebecca muttered. Sigh, such a mature, beautiful lady kneeling obediently—it was strangely satisfying.

Hearing this, Lorin tilted her head, made light fists in front of her, and softly meowed, “Meow~~~~~”

Rebecca froze. Her heart skipped a beat.

Lorin’s seductive gaze, lazy cat-like demeanor, and that fake meow blended cuteness with mature sexiness. Rebecca almost succumbed.

Rebecca was single-minded about Demon Potions, but she was still interested in women. Due to personal issues, she’d ignored such things before. Now, her throat tightened. She tried to swallow—but her mouth was dry. Enough! She couldn’t play along anymore.

“Ahem… alright then, you can follow me…” Rebecca said.

Sigh, it was hard to describe Rebecca. Recruiting a Blood Clan member without asking skills, just charmed by beauty… truly…

“Wonderful, Master~~~” Lorin leaned down, gently removed Rebecca’s shoes and socks, and kissed the tip of her smooth toes.

Rebecca didn’t stop her. She knew this was a Dark World loyalty ritual. But… a girl’s feet are sensitive. Lorin’s warm yet cool hands made her feel ticklish, with an indescribable sensation. Yet, it ended too soon.

After that, Lorin did something even more surprising.

Before Rebecca could react, Lorin’s nails grew long and sharp, slashing her own hand.

Blood splattered but didn’t fall. It coalesced mid-air into a blood-formed magic circle.

“Master, please accept Lorin’s heart…”

Rebecca recognized it—the Blood Clan’s blood slave pact. Voluntarily offering essence blood created an absolute master-servant bond. The Blood Clan could never defy the drinker.

“Are you sure… about this?”

“I trust you won’t abandon or harm me, Master!” Lorin smiled slightly.

Compared to the eternal loyalty and lost freedom the Blood Clan sacrificed, the master faced no constraints. This pact was an anomaly in contract magic.

“Alright then…” Rebecca didn’t mind taking her in—not as a slave, but a companion. Well, truth be told, she was attracted to her. Having such a beautiful vampire around was nice~ especially since her role was crucial for Rebecca.

Rebecca parted her lips slightly. The blood circle transformed into a thread and flowed into her mouth.

It tasted sweet? Rumors were true—Blood Clan blood was delicious. But it held immense energy; ordinary people drinking it would turn monstrous.

After Rebecca drank, Lorin felt a soul-deep tremor. She felt fused with Rebecca.

“Master… Master… wuwuwu…” Lorin sobbed with joy, hugging Rebecca tightly.

Rebecca smiled faintly, gently stroking Lorin’s head. “There, there…”

When a Blood Clan became a blood slave, emotions turned chaotic briefly. Rebecca didn’t know this, but seeing Lorin disoriented, she comforted her softly.

After a long while, Lorin snapped out of her daze. She struggled up and bowed deeply.

“Master~~ Meow~~”

“Uh… um… stop meowing…” Rebecca’s head throbbed slightly.

“Why? Doesn’t Master like cats?”

“I do… like them… but you can’t… keep doing it…” Rebecca said helplessly.

“Oh, understood~ Master~~” Lorin replied obediently.

Such a mature lady being so obedient was thrilling—that look inviting anything… ahem…

“Uh… I skipped class… remember to cover for me…” Rebecca said.

“No problem~~” Lorin smiled.

“Mhm~” Well, that was Rebecca’s plan. Since Lorin managed her class like a homeroom teacher, skipping didn’t matter. If she didn’t report it, Rebecca was safe~

“Master~”

“Hmm?”

“Nothing~ hehehehe~” Lorin’s suppressed joy made Rebecca smile.

“I’m off~ little kitty~” Rebecca rarely joked, but Lorin’s genuine nature amused her.

“Aiyaaaa~~” Lorin covered her face shyly, acting coquettish.

Rebecca just shook her head with a smile and left the office. She had things to do today.
