Yumesaki Anzu

Haruki's older sister.

Although timid and quiet, she's also very kind. Even more clueless than Haruki, but she always tries to act the older sister in front of him. Born with a frail body, she's spent the better half of her life on a hospital bed. She loves to look after people, and loves her little brother. Because she barely goes out, she enjoys dreaming up fun fantasy worlds.
