Riku Nanase  

, 七瀬 陸

Although there may be times when he appears clumsy, this individual is known for their honesty and diligence in their work. Despite having a weak constitution from an early age, they have found pleasure in watching shows while battling their illness. Spending most of their time in the hospital has made them somewhat naive about the world outside. They frequently argue with Iori, but since they haven't had many opportunities to engage in such conflicts before, they actually enjoy the experience.
