Naru Kotoishi

琴石 なる
She is an energetic and cheerful kid who likes to play around. She keeps coming to Seishuus house and doesnt seem to understand personal space. She also has a lot of friends. Even though she can sometimes be seen as annoying by Seishuu. She properly apologizes if he gets really mad. She may have a possible crush on him since she was worried when she considered the possibility he might have a girlfriend. She also likes to collect strange things such as bugs and shells from the beach with slugs and other creatures still living inside them. She is also rather adventurous as shown in the first episode and chapter where she continually climbs over a tall wall despite the danger to see a beautiful sunset. She has a bad habit of imitating the behaviors and language of the people she sees which causes her to say words she doesnt understand that are rather inappropriate.
