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.
