Masaharu Tsuwabuki

Nanatsuiro Drops’s Protagonist. A quiet boy who rarely talks to anyone, including his friends. In the beginning of the series, he bumps into Sumomo Akihime, causing her to splash him with water. After the accident, he is inducted into the Gardening Club by Natsume Kisaragi. Later, he receives a mysterious beverage when he bumps into a human-looking Figurare creature carrying a bag full of potions, causing them to switch cans, which transforms Masaharu into a stuffed lamb doll. Kisaragi finds him and applies a second potion, allowing him to move and talk. In order to change back, he must work with his partner, “his chosen girl”, who happens to be Sumomo. In order to change back, he must collect seven stardrops without telling her his true identity. It is revealed later on that the transformation potion is tied to phases of the moon. During the day he reverts to his human form, but just after sunset he changes to his stuffed animal form. It is also revealed that on the night of a full moon, he will remain in his stuffed animal form for twenty-four hours, but on the night of a new moon, he will remain human for twenty-four hours, granting him some semblance of a normal life.
