ISEKAI The Otherworlder’s HeirVolume 2 The Promise View all volumes
A promise torn from chaos. A mechanism set in motion.
The Promise continues the saga ISEKAI The Otherworlder’s Heir, where The Inflection left off: in a world where every choice can change everything, and where appearances conceal unsuspected dangers.
Arius Lovelace, a young baron on the run, has earned respect… and solitude.
During an imperial convoy, an attack blurs the lines. Betrayals, illusions, missing children: Arius must protect far more than his own life, just as the shadow of a greater conflict begins to close in around him.
Between quiet duels and whispered promises, he surrounds himself with emerging friendships, unsettling glances… and truths he was not ready to face.
On the road back to his principality, Okame Nepeta — a nekomimi with a crystal-clear laugh — becomes his companion in flight, in play… Yet in the shadows, an unseen guild moves its pieces.
What once seemed like a game becomes a trap.
And a word given may seal far more than a destiny.
What you will find in this volume
A tighter pace: attacks, convoys, grey zones, and threats that constantly shift.
A web of intrigue within the Kulia Empire, where alliances and betrayals blur together.
A central dramatic thread: missing children, traps, illusions — and a truth drawing closer.
A relational dynamic: complicity, tension, and a budding romance, without erasing the danger.
A promise that carries an unexpected weight.
ISEKAI The Otherworlder’s Heir — The Promise blends adventure, humor, romance, and dramatic tension in an immersive isekai where every smile may conceal a trap.

Arius Lovelace
Baron/Principal protagonist
The bedroom door burst open. Arius entered first, shoulders slumped, visibly drained from training. In the hallway doorway, Dominica stood motionless. The elf observed the young heir with her usual calm. “Five minutes, Master Arius,” she said simply. “Then training resumes.” The boy nodded without enthusiasm. “Yes…” He closed the door behind him. No sooner…

Elora Aelwyn
Traveling companion and protector of Arius
The wind stirred the high branches of Wolfendre, and the whisper of leaves nearly drowned out the light steps moving across the living walkways. Here, there were no stone walls, no bastions raised against the forest. Dwellings rose from ancient wood, patient and reverent, as if offered by the trees themselves. Elora Aelwyn grew up…

Granddon
Chief mage to the Marquis of Sinevergo
The rumor had spread even before the exercises began. Five mages. Five. And not a single one had managed to cast even the simplest spell. The accounts varied. Some spoke of speed.
