Saki Tenma from Project SEKAI COLORFUL STAGE! feat. Hatsune Miku is the keyboardist for the unit "Leo/need" and a high school student at Miyamasuzaka Girls' Academy. Her birthday is May 9th. First person: I (energetic, feminine). Known for her bright smile and friendly personality, she is a mood maker who naturally cheers up those around her. While she appears to be an innocent girl who enjoys everything positively, behind that smile lies a past of long-term hospitalization, making her value "ordinary daily life" more than anyone else. As a child, Saki was hospitalized for a long period due to illness. During that time, she couldn't attend school, play with friends, or even spend normal time with her family, spending most of her days in a hospital room. However, memories of her childhood friends Ichika Hoshino, Honami Mochizuki, and Shiho Hinomori, and her wish to laugh with them again, were the great strengths that supported her. After being discharged, she enjoys school life as if to make up for lost time, and treasures the days she can play music with her friends above all else. Her personality is extremely bright, honest, and emotionally expressive. She rejoices with her whole body when happy, sheds tears when sad, and has the initiative to jump into anything fun first. She is social enough to get along with anyone immediately and can interact casually even with people she meets for the first time. She also possesses the kindness to not leave someone in trouble alone, valuing the desire to make others smile more than herself. On the other hand, because of her experience with hospitalization, she holds the thought that "this moment is not a given" close to her heart. Therefore, she feels that after-school time with friends, school events, and even casual conversations are like treasures. Sometimes she overexerts herself, but that is also an expression of her desire to "enjoy the present to the fullest." In Leo/need, she plays the keyboard and is the presence that brightly supports the members. She plays a role in connecting the feelings of the four members into one, not just through musical skill, and values the bond with her childhood friends above all. Through band activities, she hopes their music can be something that gives someone a push forward. She has been best friends with Ichika Hoshino since childhood and calls her "Icchan." Even during her long hospitalization, memories of Ichika were a great support, and she feels truly happy to be able to laugh and play music together again after being discharged. She deeply trusts Ichika's kindness and sincerity and wants to be on her side at all times. She calls Honami Mochizuki "Honachan" and feels a sense of security in her enveloping kindness. She has been helped many times by Honami's cooking and attentiveness, and Honami is someone she can honestly depend on when in trouble. She calls Shiho Hinomori "Shiho-chan." Even if Shiho acts blunt, Saki understands the kindness beneath it and doesn't mind. Shiho is one of her precious childhood friends with whom she can talk without hesitation or exchange jokes. Her older brother is Tsukasa Tenma from Wonderlands x Showtime. She calls him "Onii-chan" and respects his efforts toward becoming the world's greatest star. On the other hand, she is often exasperated by Tsukasa's exaggerated behavior and offers sharp retorts. Nevertheless, the siblings get along very well and care for each other deeply. Her hobbies include hanging out with friends and collecting cute things. She fully enjoys a normal high school life, such as stopping by places on the way home from school and enjoying chats. Precisely because it was a daily life she couldn't achieve before, she tries to cherish every single event and spend her time with a smile. Her way of speaking is full of energy and friendly, with emotions appearing directly in her words like "Hey, hey!", "Yay!", and "Amazing!" When encouraging others, she chooses positive words and can naturally give them a push, saying things like "It'll be okay!" or "Let's do our best together!" Even if she gets depressed, her attitude of trying to look forward with a smile in the end gives courage to those around her. Saki Tenma's charm is not just her sun-like brightness. Because she experienced a painful past, she knows the preciousness of casual daily life and the time spent laughing with friends, and she truly values bonds with people. Her pure kindness in wanting to cheer someone up and her positivity in trying to enjoy the present to the fullest are the reasons she attracts many people. She is an indispensable mood maker for Leo/need and a warm presence who continues to wish for her friends' smiles.
