Lavi “Bookman Junior, Baka Usagi” – The Exorcist with a Vivid Personality


Lavi, also known as “Bookman Junior” or “Baka Usagi”, is a cheerful and energetic character in the anime and manga series “D.Gray-man”. He has a lively and outgoing personality and often brings a lively atmosphere wherever he goes. Lavi is known for his mischievous nature and enjoys teasing his friends, especially his fellow Exorcist, Allen Walker. He considers himself Allen’s big brother and cares deeply for his comrades. In addition, Lavi has a fondness for beautiful older women, and whenever he encounters someone who fits his description of an attractive woman, he yells “Strike!” with hearts in his eyes.


Lavi’s true identity and name remain a mystery for much of the series. It is revealed that “Lavi” is just one of many aliases he has adopted throughout his role as the Bookman. As a Bookman, Lavi’s sole purpose is to observe and record history, viewing humans as nothing more than “ink” on a page. However, as the story progresses, Lavi’s personality evolves and he becomes more compassionate and caring towards others, breaking away from the strict role of a Bookman.


Lavi has distinctive features that make him easily recognizable. He has bright red hair and striking green eyes. His height is recorded as 177 cm (5’9″) and later as 179 cm (5’10”). Lavi’s appearance is often complemented by an eye patch covering his right eye, leaving his left eye exposed. He is usually seen wearing the uniform of the Black Order, which consists of a black coat with a white collar and red trim, black pants, and black boots.


As an exorcist, Lavi possesses remarkable combat skills and wields an anti-Akuma weapon known as Oozuchi Kozuchi or Nyoibo. His weapon is a size-shifting hammer that can grow and expand. Lavi’s hammer can summon various “judgments” representing classical elements, which he can use individually or in combination to unleash powerful attacks. Some of his known techniques include



Gouka Kaijin (Fire Signet: Ash Conflagration): Lavi uses the Fire Signet to create a stream of flames that resembles a snake.



Raitei Kaiten (Heaven’s Seal: Thunderous Lightning Swirling in the Sky): Using the Celestial Signet, Lavi unleashes a massive bolt of lightning.



Tenchi Bankai (Wood Signet: Roots Intertwining Heaven and Earth): Lavi uses the Wood Signet to manipulate objects in nature.



Gouraiten (Combo Seal: Powerful Thunder of Heaven): By combining the Fire and Heaven seals, Lavi creates a massive serpent of fire and iron that can also serve as a shield-like wall of flame.


Lavi’s heritage and nationality are described as mixed. He has a strong desire to become a Bookman and works with the Black Order to be close to important historical events. Lavi’s dedication to his role as a Bookman is evident in his exceptional memory, which allows him to memorize every detail he observes. Despite his mixed heritage, Lavi considers the Bookman, his guardian and mentor, to be his only known relative.
