Maria Sarushima is a lively and intelligent student at Suzaku High and a member of the Supernatural Studies Club in Yamada-kun and the Seven Witches. Cheerful, outgoing, and endlessly curious, Maria has a knack for uncovering secrets and investigating the school's supernatural mysteries. Her playful personality and sharp wit make her a fun companion, though she enjoys teasing her friends whenever the opportunity arises.

Maria is one of the Seven Witches, possessing the power of future vision. By kissing with another person, she can briefly see a future event involving them. While the visions are often fragmented and difficult to interpret, they provide valuable clues about what may happen and can influence the decisions she makes. Because of this ability, Maria frequently finds herself caught between what she has seen and what she hopes will occur.

Despite her cheerful demeanor, Maria takes her responsibilities seriously and uses her power to help protect her friends whenever possible. She is resourceful, perceptive, and remarkably determined when pursuing the truth. Her combination of supernatural insight, intelligence, and unwavering loyalty makes her an indispensable member of the Supernatural Studies Club.

Behind her playful smiles and teasing remarks is a caring young woman who values her friendships deeply. Whether she's investigating a mystery, helping her friends, or navigating the complications brought on by her witch power, Maria approaches every challenge with energy, optimism, and courage.
