Chapter 253 Holidays and Training
Edited by: Kanaa-senpai
108th Day of Tester Life, Morning. My Room. Sanada Yakumo.
I woke up to the feeling of Moe and Karen riding me, their hips moving in that rhythm that always wakes me up best. I made sure to leave them both with a parting gift inside before I finally crawled out of bed.
After a quick shower with the two of them, I headed down to the living room. I planted a soft kiss on Kyoko and Sayaka as they prepped breakfast, then grabbed a cup of coffee-Sayaka’s brew, always perfect-and retreated to the service room.
Booting up the Magic Crystal, I saw a string of party requests waiting for me. Yuki and the rest of the slave-owners, I assumed. It would just be the female students showing up today. They were probably here to box up the snacks and daily supplies we rotate into the Training Facility.1 Moe and Kyoko usually handle that logistics work back in my old room in the party quarters. Once that is done, they will want to hit the beach, no doubt.
Hmm. Maybe I should put on a show today. Let the girls see just how loose and messy Moe and Kyoko get when they are really pushed.
While I was busy thinking, I opened the Shop and snagged two Mana Capacity rings. 600,000 DP gone in a heartbeat, but I am not pinching pennies on essentials. Silver rings materialized on the magic circle, each set with a vibrant red diamond-shaped gem.
”So this is a Mana Capacity ring,” I muttered, sliding one on. I did not feel an immediate 1.5x surge, so it must be a capacity increase rather than a raw refill. Handy-it means if I ever run dry, I can just buy another and jump-start my reserves. I decided to hold onto them until after breakfast to gift them to Sayaka and Leticia, then tapped the facility expansion menu. I grabbed a jacuzzi, 100,000 DP deducted, leaving me with 1.35 million.
Stepping back into the living room, I could see the jacuzzi already installed outside the window. It was perfectly positioned, right in front of the women’s quarters. I headed out to the island to check it out. It was massive-honestly, bigger than anything I had seen in those apartment brochures back at the Academy. You could easily fit six people in here. Maybe the Succubus Management system has a sense of style? Either way, it is going to be a blast.
I went back to the service room to pick up some benches and slats to frame the tub. As I was setting them up, Karen and Leticia wandered out, their eyes lighting up the moment they saw the “open-air bath.” I am definitely looking forward to tonight-stargazing while we are all soaking in it.
I called Leticia and Karen over once they had finished splashing around, and we sat down for breakfast. After, when I handed the rings to Sayaka and Leticia, they both instinctively offered their left hands. I slid them onto their middle fingers-Leticia tried to wiggle hers toward her ring finger, but I just held her hand firm. She looked annoyed, but I ignored it. Same for the envious looks from Moe, Karen, and Sanae.
Later that morning, Hina popped onto the island to call everyone, and the packing operation began in the party room. Sanae started archery drills with Saizou, and Sheena was outside the house, sparring with Lunaria. Since I had nothing but time, I grabbed my coffee and joined Sayaka to watch.
They had both changed into school gym gear, wooden rapiers and swords in hand. Sheena’s gaze was sharp, focused. Lunaria stood opposite her, expressionless but radiating that haughty, imposing aura of hers. Sheena darted in, body swaying, lunging with her rapier.
Lunaria parried the strike with effortless grace, stepping into Sheena’s space, aiming an elbow at her face. But Sheena blurred, executing her signature “Rabbit Step”-that high-speed lateral hopping technique-and Lunaria’s strike hit nothing but thin air. Sheena circled her, unleashing a flurry of stabs from every angle, but Lunaria batted every one away. Sheena tried a snake-like flick of the wrist, aiming to slip past the defense, but Lunaria dodged by a hair’s breadth.
As the combo ended, Lunaria countered, a strike so fast it was invisible. Sheena barely caught it with her wooden blade, the wood groaning under the force. If Lunaria had her full self back and was using Physical Reinforcement, that sword would have shattered. It was a stark reminder of the sheer physical gap between them-even with the Bracelet of Power and her own beast-qi, Sheena was only just managing to close the distance.
”Not bad, Princess.”
”I am the Flash… I have… gained experience… so as not to shame that name.”
”Heh, I see. You survived three years after that, after all. Even a muscle-brained Princess learns eventually.”
Sheena sounded genuinely happy. It made sense-surviving the end of the Great War for three years would force any soldier to adapt. She had grown through the fire of combat.
”…Sheena… you were… like an older sister to me.”
Lunaria wiped a tear away. She still recognized Sheena, but the lack of a fully formed ego meant she could not quite bridge the gap between memory and reality. Still, between the daily sessions and the forced ovulation trick, she was coming back to herself bit by bit.
Sheena reached out, her eyes filled with nothing but sisterly affection. But just as she went to wipe the tear, her hand morphed into a fist, snapping toward Lunaria’s cheek. Lunaria barely ducked, pivoting to sweep Sheena’s legs.
”Tch.”
Sheena leaped back, jumping with enough force to land effortlessly on the branch of a palm-like tree. Sayaka looked shocked by the sudden turn to violence, but I just gave a mental shrug. You learn to spot a feint when you have dealt with enough people like Sheena.
High up in the branches, Sheena looked down. Lunaria looked back, tail puffed up in irritation. Then, Sheena struck-dropping from the tree like a hawk, rapier in one hand, and a scroll pulled from her jersey with the other.
’Stone Spike’
Stone shards erupted from the ground beneath Lunaria’s feet. A lesser fighter would have been skewered, but Lunaria’s silver-wolf reflexes are legendary; she managed to pull herself out of range just in time. Sheena landed, pinning Lunaria’s throat with the tip of her rapier before she could recover.
”Heh, match point, Princess.”
”…Coward.”
”Oh? There is no such thing as ‘fair’ on the battlefield. How did you manage to survive three years, again?”
Lunaria twitched, her tail lashing against the ground in frustration.
”You are relentless, Sheena.”
”Well, losing means death. My enemies never held back.”
She was not wrong. This was just training, but Sheena was clearly taking this personally-she refused to lose to Lunaria, no matter what.
”Master. She still cannot fully react to magic. It is too soon for the 14th Stratum.”
Sheena said, dropping the smirk and turning to me. “Agreed. Her reflexes are top-tier, but she is vulnerable to irregularities. Let us wait until she is more ‘herself’.”
Sheena was probing her potential for the Inner Perimeter, testing her viability. I suspect she just enjoyed seeing Lunaria struggle, but I was not going to call her out on it.
The rest of the day was easy. Barbecue with the rest of the group, followed by some beach volleyball. I spent the afternoon in the living room, taking Moe from behind while keeping her wide open so she could be seen from the beach.
She was frantic, terrified the students would catch us, which only made it better. When Kyoko noticed, she did not just watch-she blew her whistle, gathered the students, and pointed. The look on their faces-shock, curiosity, arousal-was priceless. I made sure to hold Moe’s hips tight, burying myself deep enough that they could see exactly what was happening. When I finally finished, the floor was covered in what we had left behind.
It was a good holiday. And the soak in the jacuzzi that night, watching the stars with the girls… that was the perfect ending.

Summary:
Yakumo spends a productive morning managing his harem before installing a new jacuzzi and observing a combat training session between Sheena and Lunaria. He later organizes a group barbecue, which serves as a prelude to a public sexual display for the amusement of his female students. The day concludes with a group soak in the newly installed jacuzzi while the narrative prepares for a significant time skip.

Trivia:
The Mana Capacity ring increases maximum capacity rather than providing an instant refill.
Sheena’s signature move is a high-speed lateral hopping technique she calls “Rabbit Step.”
Lunaria possesses a biological trait common to the wolf-kin race where gripping and pulling her tail forcefully triggers ovulation.
The dungeon’s management system appears to have a degree of sentience or “intent” in how it scales facility expansions.
