About Liminal Border Part IV
Liminal Border Part IV is a single-ending visual novel that concludes the Liminal Border series. Its story takes over 10 hours and features full Japanese voice acting.
Story
With the powerful Shinonome gone, Itsuki and his allies’ business is thriving: their club, Rave, has become a major success and is generating enormous profits. But Itsuki and his best friend, Tatsuya Yorozuya, are focused on settling a score with Goro Teshigawara, the leader of the Umon-kai. They care little for the money and status their success brings, and Itsuki is prepared to risk his life to kill Goro. His business partner and childhood friend, Rin Akinashi, grows increasingly concerned about his resolve, while Luca, an executive in a foreign Mafia syndicate, draws nearer. The story follows the group’s final confrontation along the boundary between evil and justice.
Characters
Itsuki Ninomae is the protagonist. A chance encounter with a digital drug video leads him into business with his childhood friend Rin. With help from Hina, Kotoko, Meryl and his other allies, he prepares to face the Umon-kai.
Rin Akinashi is Itsuki’s longtime acquaintance and classmate, and his business partner. Popular for her looks, exemplary behavior and excellent grades, she hides a cunning nature and an intense attachment to money despite her wealthy upbringing. She and Hina run a large business, and Rin now steps out from the shadows to stand beside Itsuki.
Hina Yorozuya works with Rin to run their business. Kotoko Teshigawara, a student in the year above Itsuki, is Goro’s daughter. Though her father leads a crime syndicate, she has her own sense of justice. After learning that the Umon-kai is not on the side of justice, she joins Itsuki, becoming the public face of his business as well as a negotiator and deterrent in dealings with other organizations. She seeks to take control of the Umon-kai and impose her vision of justice and righteousness.
Meryl Hathaway, often at Kotoko’s side, belongs to an overseas Mafia syndicate. Originally assigned to watch Itsuki, she joins the group when their goals align; despite her slight build and aloof manner, she has exceptional skills in a crisis. Luca, an executive in Meryl’s syndicate, appears easygoing but has a dangerous gleam in her eyes and a fondness for sampling Japanese food.
Tatsuya Yorozuya is Hina’s older brother, a student at the delinquent-filled Badman Academy and leader of DREAD. After Itsuki negotiates to have his parents’ debt to the Umon-kai written off, Tatsuya and his associates help run Itsuki and the gang’s club. He considers Itsuki a friend and is determined to stand by him as they work to bring the Umon-kai to an end.
Shoji teaches at Badman Academy and regularly visits Rin and Hina’s business. His connections among its other regular customers make him a useful ally to Itsuki and Hina. Despite his unusual preferences, he is described as good at heart and well-connected among wealthy circles. Goro Teshigawara leads the Umon-kai and is Kotoko’s father.
