竜宮 レナ

Rena is a classmate of Keiichi's. She is quite interested in his everyday life, possibly because of an inherent urge to look after people.

She comes with the standard-issue honesty, earnesty and blushes that you find in many heroines.

However, her only reward for taking care of Keiichi is an incessant series of pranks. It really is unfortunate for her.

She likes anything and everything she considers adorable, and this is also a very typical trait in a heroine.

But that is also her greatest weakness...

Rena originally called herself Ryuuguu Reina, being born and raised in Hinamizawa. Her family moved to Ibaraki for her mother's work. After her parents divorced, Reina's mental state deteriorated to the point where in 1982 she went on a rampage destroying windows in her school and attacked three students, permanently blinding one of them in one eye. She claimed to hear Oyashiro-sama telling her to return to Hinamizawa, believing she was cursed for leaving the village in the first place.
