Dungeon And Slave: The Lustful and Violent Slave Harem of the Guard and Students Chosen as Testers for the Succubus Dungeon - Chapter 16: Siscon and Mana Rank-Up

Chapter 16: Siscon and Mana Rank-Up

Tester Life Day 4, Test Dungeon First Floor, My Room, Third-Year Tomoya Yuki

“Distribution’s done? Then we’re dismissed.”

“““Good work!”””

At my signal, everyone raised their swords, spears, and bows to their chests before heading to their My Rooms.

I dragged my tired body back to my My Room, set my short spear by the door, and dropped my backpack.

Stripping off my uniform, I changed into tracksuits, bought a sports drink from the shop, sat on the bed, and took a breather.

After about 10 minutes, I stood, grabbed a bucket, body soap, shampoo, a towel, and spare underwear, and left for the fountain.

Clubmates were at the fountain, stripping down. I sat beside them.

They were talking about summoning Wall Butt tonight for the first time in two days.

Ignoring their chatter, I washed my body with cold water. The fountain’s stone rim had a groove that somehow absorbed wastewater, keeping the area dry.

After washing my hair, I quickly dried off, changed into fresh underwear and tracksuits, shivered, called out to my clubmates, and returned to My Room.

Back inside, I picked up my backpack and cashed in the magic stones.

“Seven hours for 14 stones…”

Six hours of fighting, minus breaks, for this? More than yesterday, but I slumped at the low income.

The Battle Sports Club totaled 145 stones, split evenly among 10, with extras saved for emergencies.

Ten might be too many.

Other students and club groups form smaller parties.

Teachers have six. Karate Club has three six-person parties.

Kendo and archery clubs merged, forming seven parties of 6–7.

Kickboxing Club has two parties—six and eight.

Kickboxing’s split into elites and backups, though.

I don’t know who named them Horn Rabbits, but we kill about the same as other clubs—probably more, since we go deeper. Yet, our per-person stone share is less, cutting DP income and other benefits.

Some teachers, karate, and kickboxing members got shower rooms on day two. None of us did.

Apparently, you need to cash in 20 stones at once, and it was first-come, first-served for 10 people.

As expected, mana’s harder to raise.

Teachers and active six-person parties hit G+ yesterday morning, while we only reached G+ today.

We entered the dungeon early on day one, killing more Horn Rabbits than anyone.

If kills are equal but mana growth differs, experience points must be divided by party size.

We need to kill nearly twice as many as smaller parties.

“It’s really like a game.”

When we were abducted, I was confused, then furious. I rallied the club, bought real weapons—not competition replicas—and felt thrilled yet terrified in our first life-or-death fight.

Our club’s foundation and info from earlier dungeon entrants let us fight.

I never thought joining the Battle Sports Club would pay off like this.

I’ve always loved medieval Europe, so I joined the club to practice its popular sword-and-spear combat sport. I chose this academy for its Battle Sports Club.

It’s niche in Japan, but our club drew manga and anime fans who loved medieval Europe. We studied videos with seniors, went to matches, used hand-me-down or self-bought weapons, and borrowed martial arts club protectors. I won the national championship in my third year’s summer.

That foundation helped, but day one was tough. By day two, we saw Horn Rabbits’ attacks were predictable. Stay alert, and they’re not scary.

We’ve pushed deeper and killed more than anyone since.

Side tunnels are rough, though.

Unlike the wide main route, side tunnels are narrow, giving less time to react to Horn Rabbits. We have to stay on edge.

We got injuries the moment we entered, making it brutal.

Luckily, a chest potion let the injured move.

“To increase shares, we should split into two five-person parties.”

Hmm… Five can handle two rabbits on the main route, but side tunnels are tough, and three or four rabbits would be too much. Like other parties, we need two front-liners, two rear guards, and one per side—six minimum. Splitting would scatter our strong members.

Morale’s an issue. Except for me and a few, most aren’t desperate. Some help me, but others would resist fewer members and higher risk, especially since they’re already scared of side tunnels.

This way, mana and income stay low.

To earn more with 10, we’d need the next floor. New monsters might have higher-value stones.

But we haven’t found the stairs. They’re not on the main route, so side tunnel exploration is unavoidable.

Other clubs are still leveling on the main route, so no one’s found them.

I’ll need to convince everyone to explore side tunnels and extend hours. My stamina’s up since hitting G+ this morning. Yesterday, I was wiped after returning, but today’s better.

“I’ll talk to them tomorrow.”

I’ll propose side tunnel exploration and longer hours.

Deciding tomorrow’s plan, I bought the cheapest breakfast set and ate.

Then, I opened the Slave purchase screen and tapped Wall Butt Succubus, displaying the courses.

“Wall Butt, huh…”

A clubmate who tried it the day before yesterday said even the 300 DP course was satisfying, boasting three rounds without pulling out. The magic crystal shows a cute succubus’s face, doubling the excitement.

I’m jealous.

I’ve been horny since morning. Others who hit G+ a day earlier said the same yesterday—maybe a side effect of boosted physical ability. It makes sense; my strength and stamina are up.

Wall Butt’s tempting, but I can’t waste DP. I need to save my sister faster than anyone.

Otherwise, my precious, cute sister will become someone else’s sex slave…

“No way that’s happening!”

I slammed my fist on the desk.

My sister, Hina, is a first-year who just enrolled. Small, cute, an innocent angel. I won’t let her become a beast’s sex slave!

I switched to the Slave catalog.

Fixing my gaze on Hina’s bust-up photo, my eyes teared up.

“Hina… my sweet Hina. Hold on, your big brother will save you.”

Tracing her face, I noticed “Grade 2” above her row.

I frowned.

“Tch, why’s Hina Grade 2?”

No matter how I look, it’s unacceptable.

How’s my adorable sister not Grade 1? That’s absurd. Do succubuses and humans have different aesthetics?

No… I know why.

The difference from Grade 1 girls: breast size.

Hina’s a beauty, maybe the world’s best. But her chest is small. To an erotic succubus, that’s a demerit.

“They don’t get it.”

I closed my eyes, shaking my head.

Succubuses can’t appreciate small breasts’ charm.

“But… it makes her easier to save.”

It’s infuriating she’s not Grade 1, but 500,000 DP cheaper helps.

“Still, 1,500,000 DP.”

One stone is 30 DP, so 14 stones daily is 420 DP. Breakfast sets cost 150 DP, leaving 270 DP daily.

At this rate, I’ll never save Hina.

I have to reach the second floor first.

“Come to think of it, that guard had good gear.”

I recalled the guard I often see.

Probably from chests, but his gear’s too complete.

Maybe because he’s solo. If we get 420 DP daily with 10, he earns 10 times that. No wonder his gear’s stacked.

“But taking those rabbits alone?”

We’re used to two now, and I could manage solo if I tried.

Three would be dicey—probably get injured.

I remembered the animation department otakus who entered the dungeon first on day one, limping back, clutching stomachs.

They had bad bruises, maybe cracked bones, teachers said.

They haven’t left their rooms since.

Thanks to them, we knew about horned rabbits and their attacks, but I don’t want to end up like that.

Long-term, solo’s impossible.

The guard’s strong, so he’ll probably manage. His demeanor screams strength. Those eyes are wild.

I know those eyes—my great-grandfather, a war veteran, had them. Eyes of someone who’s killed. In Japan, only yakuza or lunatics joining foreign mercenary units have them.

That guy could solo the second floor or beyond. Solo, he’ll buy Slaves way faster than me.

He’d definitely try to buy Hina.

“No, no, no!”

I won’t allow that!

Kill him now? Impossible. Even with the whole club, I doubt we’d win. After day one’s reactions, everyone but me would balk.

Then what? Beg him not to buy her? That might make him notice her. I heard he beats up students he dislikes. Kickboxing Club guys got pummeled in “sparring.” He’s close to the chairman, so he’s untouchable. Asking that jerk might make him buy Hina out of spite.

If he’s into big breasts, maybe he’ll skip her… There are Grade 1 Slaves. There’s a slim chance he won’t buy her.

“Push forward.”

I need to outpace the guard and save Hina first. That’s the surest way.

The guard has an early lead, but as everyone’s mana rises, our numbers will give us the edge. We’ll fight stronger monsters for more income. That’s it.

“Hina… wait for me. Your big brother will save you.”

Gazing at my beloved sister’s catalog photo, I renewed my resolve.

Tester Life Day 5, Test Dungeon First Floor, My Room, Yagumo Sanada

The alarm woke me. I took a cold shower, calming my raging morning wood.

Buying two breakfast sets, I ate veggie sandwiches, sipped coffee, and recalled last night.

“Yesterday was great.”

No excessive draining—I went at my own pace.

The first and second Wall Butt girls looked high school-aged, not too experienced.

Their bodies were stunning, with C–D cup breasts, perfect for grabbing. Their pussies, maybe standard for succubuses, guided my cock deep and milked me post-ejaculation, feeling amazing. I did two rounds each.

The third was a shy, middle school-aged loli who stirred my protective instincts. I was relieved it wasn’t the tanned succubus.

She seemed inexperienced, maybe scared, possibly roughed up by other testers. So, I fondled her A-cup breasts, went down on her pussy, and took my time with foreplay, finishing one round. Five rounds total, and I was satisfied. I spent the remaining time stroking her buttocks and tail.

The usual mischievous masochist succubus is great, but trying different types is Wall Butt’s charm, I realized again.

“Now, has it gone up?”

My intense morning wood and lighter body suggested a mana increase, so I checked with Mana Measurement.

Sanada Yagumo

Age: 25

Race: Human

Mana: E

“Oh?”

It went up.

Yesterday’s 200 kills must’ve maxed out my experience.

I need to check how many Wind Cutters I can cast now.

That spell’s useful, but low cast limits are a drawback. Hopefully, the mana boost helps.

After checking, I let my stomach settle, bought bento, and put on my enhanced guard uniform.

Equipping my leather armor, gauntlets, and shin guard, I grabbed my iron small shield and machete, leaving My Room.

Outside, the plaza was busy as usual—students washing faces, groups strategizing. I entered the dungeon, passing fighters, and headed to the transfer room.

On the second floor, I went to where I stopped yesterday.

A Horn Rabbit appeared, so I tested magic, but couldn’t gauge mana drain like yesterday. After a few casts and a Physical Enhancement for good measure, I concluded:

“It’s doubled.”

I can feel I could cast Physical Enhancement 10 times in a row. F was 3, F+ was 5, but E jumps to 10. Alphabet rank-ups spike mana big-time.

Standard Wind Cutter uses about half Physical Enhancement’s mana, so I can fire 20 in a row.

From G to F… G couldn’t cast Physical Enhancement. F’s big mana jump enabled it.

F+ to E doubled my mana. If that continues, F to E is a huge gap.

I fought three-rabbit groups without magic to test.

“I see.”

My base strength’s way up—like I’m using Physical Enhancement.

So, monsters from F+ to E will spike in difficulty. Third floor? Or fifth and beyond?

Can’t let my guard down.

For now, it’s just Horn Rabbits. Time to grind experience.
