"Alice in the Country of Hearts: Love Labyrinth of Thorns" is a manga adaptation of the visual novel "Alice in the Country of Hearts," written by QuinRose and illustrated by Mamenosuke Fujimaru. The story centers on Alice Liddell, a young woman who is transported to a fantastical world known as the Country of Hearts after following a white rabbit. This world is populated by anthropomorphic characters inspired by Lewis Carroll's "Alice's Adventures in Wonderland," but with a darker, more romantic twist.

Upon arriving, Alice learns that she has been chosen as the "outsider," a role that grants her immunity to the rules of the world, including the inability to die. The inhabitants of the Country of Hearts are divided into factions, each led by a charismatic and often dangerous figure. These factions are in constant conflict, vying for power and influence. Alice becomes entangled in their struggles, particularly with the leaders of the four major territories: the Hatter Mafia, led by Blood Dupre; the Clock Tower, overseen by Julius Monrey; the Amusement Park, ruled by Boris Airay; and the Castle, governed by the enigmatic Queen of Hearts.

As Alice navigates this strange world, she forms complex relationships with the male characters, each of whom harbors their own secrets and motivations. Blood Dupre, the mafia boss, is both charming and ruthless, while Julius Monrey, the clockmaker, is aloof and introspective. Boris Airay, the playful and flirtatious cat, contrasts with the stoic and mysterious Nightmare Gottschalk, who serves as the Queen's advisor. The Queen of Hearts herself is a volatile and unpredictable ruler, adding tension to the political landscape.

The narrative explores themes of identity, loyalty, and the nature of love, as Alice grapples with her feelings for the various characters and her desire to return to her own world. The "Love Labyrinth of Thorns" arc specifically delves into the darker aspects of the Country of Hearts, emphasizing the thorns that symbolize the pain and complexity of love. Alice's journey is marked by moments of introspection and conflict, as she questions her place in this world and the true intentions of those around her.

The manga retains the surreal and dreamlike quality of its source material, blending whimsical elements with a more mature and emotional tone. The characters' interactions are layered with tension and ambiguity, reflecting the intricate dynamics of the world they inhabit. Alice's growth is central to the story, as she learns to navigate the labyrinth of her own emotions and the challenges posed by the Country of Hearts. The series concludes with a resolution that ties together the threads of romance, intrigue, and self-discovery, leaving a lasting impression on the reader.
