Nine Soulmate bonds. A stat sheet that makes dungeon bosses flinch. I’ve come a long way from the pact-immune nobody who walked onto Night Campus with nothing but immunity and nerve. If you haven’t started this journey yet, begin with Book 1.

A distress call arrives from an ocean-dimension academy that’s sinking into the sea. Over two hundred trapped. Islands drowning one by one. And my Realm Core Attunement makes me the only person who can stabilize the failing anchors before they all go under.

The whole harem deploys.

Corridors that flood without warning. Bridges swaying over crashing waves. A grand staircase called the Drowning Steps that loses more of itself to the water every day, counting down how long everyone has left.

And waiting there: Nerida.

Brown skin with a pearlescent sheen. Eight powerful tentacle-limbs below her waist that move before her mind catches up. Bioluminescent markings that pulse violet-pink when she’s turned on, whether she wants them to or not. She’s been holding this dying place together alone for two years, trusting nobody, surviving on math and stubbornness. When her tentacles reach for me before she can stop them and her whole body lights up in the darkness, the woman who controls every variable discovers what happens when she finally lets someone else take charge.

Her eight-point grip is nothing like anything I’ve felt. Multi-directional. Independent. Relentless. Suction cups that latch and pulse along every inch they touch. And she cannot hide a single thing her body feels.

The women who’ve been with me since the beginning? They bring everything.

Roxy, my violet-haired exhibitionist, finds ways to lift morale that only she would think of. Elowen, the thicc librarian with inky horn-tips and spectacular curves, takes one look at the failing ward network and starts giving orders. Tamsin, ice-queen prefect with glowing fertility sigils, discovers her maternal side comes with tactical advantages. Maelia, the voluptuous MILF headmistress, holds political coalitions together when half the faculty wants to give up. Vyra, my athletic silver-haired rival, learns that underwater fighting suits her just fine. Lyric, the corrupted angel with sapphire eyes and hidden curves, channels devotion into emergency rituals. Nyx’tara, obsidian-skinned goddess with three thousand years of memory, recognizes architecture from before even her time.

And Ssylara, my emerald-scaled naga with the fifteen-foot tail? The ocean is finally her element. For the first time, she’s the most capable person in the room. And when her body decides this is the moment for something she can’t control, she makes a choice that turns vulnerability into raw power.

Someone wants to prove that bonds are weaknesses waiting to be exploited. And the terrifying part? His argument makes sense.
