Though her voice is soft, she is very energetic, and will immediately say "yes" if she's asked to play some games. She is so energetic, it's annoying. Nevertheless, Reiha is a good friend and would rather get hurt than betray her friends. Curious and protective, she spies on her siblings to see if they're doing... things. She is also adventurous and even goes to places she's curious about.
Her creator gave her the nickname "Ishtareiha" because of she has a resemblance to Fate/Grand Order's Ishtar (it was a coincidence). It also has become the name of the "demon" inside her.
Her ahoge is detachable. However...
Reiha has another persona; rather, a monster inside her, who is awakened when you pull her detachable ahoge. When the monster awakes, her eyes turn gold and her hair forms into a bunch of snakes (like Medusa). The only way to make her go back to normal is to attach her ahoge to her head; however, when she does go back to normal, she falls asleep for the whole day.
The snakes forming her hair (in monster form) are very poisonous when they bite.
She was supposed to be a blue-themed UTAU, and her original name was Reiha Aone. However, the creator decided black and red for her instead.
She likes playing sports, however, her absolute favorite is baseball.
Reiha and Yuren both play Fate/Grand Order. She has a lot of SSR Servants!
She has a weakness for black forest flavored cakes.
Really bad at math.
Her ahoge moves depending on her mood. It sways back and forth when she's happy, it will look like it's a wilted plant when she's sad, it stands erect when she's angry, etc.
