Shizuka Nanahoshi

ナナホシ・シズカ
Due to her desire to go back home and her unattached attitude to her current world, she tends to like being alone. She is serious when working and childish when it come to stuff from the old world. Shizuka spends all her time indoors and doesn't like meeting people as she doesn't want to grow attached to anyone in the current world. (Source: Mushoku Tensei Wiki)
