Sarina Tendouji

Sarina Tendouji (さりな) was a pivotal character in the Oshi no Ko manga series. She was a child patient under Gorou Amamiya's care and a fan of Ai Hoshino, which rubbed off on the former. Following her death from anaplastic astrocytoma, she ends up being reincarnated as Ai's child, Ruby.

Appearance
Sarina had wide pale-blue eyes and shoulder-length hair. However, towards the end of her life, she gradually lost her hair and presumably became bald as her condition worsened due to her sickness: anaplastic astrocytoma.

In the majority of her appearances, Sarina wore a wool hat with a heart pattern on its brim, adorning it with a bunny pin, Ai Hoshino's signature symbol.

Personality
On the surface, Sarina appeared energetic despite her illness, especially when talking about her oshi, Ai Hoshino, or teasing Gorou Amamiya. Sarina was very passionate about Ai, having watched all her recordings and memorized her choreography down to the smallest details.

However, because of her illness, Sarina was depressed by her inability to move as she pleased and became scared of falling, subconsciously bracing herself to fall whenever she attempted to walk by herself. This fear carried on to her next life as Ruby Hoshino, but she managed to overcome it thanks to Ai's guidance.

 * 咲梨菜 - "blossom" (咲) (sa), "pear" (梨) (ri) and "vegetables, greens" (菜) (na).
 * 紗利奈 - "thread, silk" (紗) (sa), "benefit, advantage" (利) (ri) and "apple tree" (奈) (na).
