Yuuji Takashima is the primary coach guiding Tazusa Sakurano's training as she strives for Olympic qualification in competitive figure skating. Following her parents' divorce, he lives with Tazusa and her younger sister, Yōko Sakurano, serving as their guardian and providing a stable home environment. Professionally, he maintains a consistently supportive and encouraging demeanor, consistently emphasizing Tazusa's potential even during competitive setbacks. His coaching style focuses on positivity, leading to recurring comedic misunderstandings as he interprets Tazusa's outbursts directed at the ghost Pete Pumps—who possesses her—as stress-related reactions aimed at himself.

He displays considerable patience in managing challenges to Tazusa's public image, particularly her strained interactions with the media and skating officials. He collaborates with figures like reporter Kazuya Nitta to mitigate negative press and support Tazusa's career trajectory. In his personal life, he has a relationship with a woman named Hitomi, whom he later reveals as his fiancée during the series.

While primarily depicted through his professional coaching role and guardianship duties, his character remains steady and compassionate throughout the narrative. His engagement marks a notable personal development.
