This marks the beginning of a whole new life for Ein, and he’s out to prove that he’s worthy of the crown.
Ein begins a new chapter of his life at the academy, where he’s forging friendships and honing his swordsmanship. Krone, too, is doing her best to become the crown prince’s ideal partner. But academy life isn’t all studies and school-day shenanigans! Ishtarica is soon besieged by malicious schemes and the terrifying Sea Dragon. Against everyone’s wishes, Ein decides to face the legendary beast head-on! With his new life and homeland in jeopardy, the boy-turned-prince is willing to put it all on the line!
While serving as the king’s proxy in Euro, Ein unexpectedly crosses paths with Glint and discovers that Heim’s third prince has been desperately searching for Krone! Then after a startling incident devastates the Ishtarican royal family, Ein must face the true nature of his power. With his loyal allies alongside him, Ein ventures to Magic City Ist for answers, but soon learns that all is not well within the city’s streets; a rash of kidnapped orphans has Ist’s citizens cowering in fear. The prince starts working with chief researcher Professor Oz in exchange for information in hopes of finding the culprit. Can Ein solve the case behind the kidnappings? And will he discover that there may be more to Professor Oz than first impressions imply?

However, the boy quickly learns that his fox hunt is about to get rocky when a series of earthquakes shakes up his plans. In the hubbub, a primordial beast suddenly rears its head and it’s starving to exact revenge against the crown prince and royal family! If the first king couldn’t slay this ancient monster, what hope does Ein have? And just what is lurking within the shadows of the Demon Castle? The crown prince’s journey is nowhere near its end—it’s just getting started.
White Night Castle is shocked by the Ein’s sudden and drastic growth spurt. Only he and his grandfather know the truth behind this metamorphosis, but they have vowed to keep it a secret. Meanwhile, Ishtarica prepares to settle the score with Heim, and the royal family is dispatched to a neutral island for further negotiations. However, Warren appears to be especially wary of this course of action. Following an exhausting battle of wits, Ein and the royals return to home to discover that Magna has been nearly burned to the ground. Just what happened while the crown prince was away? And does he have a hope of saving the now-ruined city?
When summoned by the Elven chief, Ein makes the trek to the village of Syth Mill to meet with her. This wise elf was once close with Jayle, Ishtarica’s First King, and she claims to know a thing or two about the red foxes. With his trusty knight Chris by his side, Ein learns of a sealed shrine nestled deep within the village’s holy grounds. But just as our crown prince solves the mystery of this shrine, he discovers that Syth Mill has completely transformed. Meanwhile, a mysterious string of noble kidnappings has left Heim in shambles. With no end in sight to these terrors, one has to ask: who’s behind all of this? When Elena stops to ask this question herself, she comes to a horrific realization—Heim may not be the kingdom she once thought it was. Now scared for her life, the noblewoman no longer knows whom she can trust.
As Ein delves deeper into Ishtarica’s greatest secrets, he’s suddenly reminded of the legend Professor Oz once shared with him. The prince tries to connect these puzzle pieces when he receives a troubling report from across the ocean—Heim is gearing up to invade its neighbors while Euro has been overrun by mysterious creatures known as chimeras. Unable to let these heinous acts slide, Ein and the Ishtaricans quickly take action against Heim’s devious machinations. But while doing so, the crown prince comes face-to-face with a shocking revelation regarding his most trusted confidants. Can Ein save the world and destroy the roaming chimeras, even with the deck so stacked against him? And more importantly, can he find the strength to stand on the front lines of a grisly war in order to protect his loved ones?
Just as he’s about to set foot in Heim, Ein steels himself for what is sure to be a gruesome battle—one that will settle a feud that has gone on for long enough. As the Ishtarican-Heim conflict escalates, however, questions surrounding the red foxes’ endgame hang over the battlefield. But the crown prince quickly realizes that his first war will be full of surprises when he’s thrown into combat against his father, Rogas—the very man who taught him how to wield a sword. But the familial in-fighting only intensifies when Ein’s brother proceeds to stand before his blade. Fully aware of the tall order ahead of him, the crown prince must brave these hardships in order to vanquish the foxes once and for all. He vows to fight until the bitter end, even if he falls in the process. Will justice prevail? Or will the royal family’s second Demon Lord make the same mistakes as his predecessor?
