Maguro Sasaki

Maguro Sasaki is a college student. He lives in the Suzuran Shopping District with Ringo, as the eldest son of a fishmonger. He is Ringo's childhood friend, and frequently spends time with her in the physics clubroom, though he does not appear to be interested in conducting experiments himself. He is reportedly to be skilled at studying, cooking, and games. He constantly carries a Puyo-themed kendama, a toy similar to a yo-yo or ball-in-cup, as he is an avid gamer; the tricks he performs with this toy comprise his attack animations. He has a unique quirk of adding ★ at the end of his sentences.

Maguro lives in Suzuran like Ringo and Risukuma where his family runs a fishmongery. He has one younger brother. Maguro is a guy who's most distinctive feature is his purple hair that covers his eyes. His eyes are never shown, which in Puyo Puyo!! 20th Anniversary is suggested to be a fail-safe measure so he doesn't accidentally infatuate everyone, due to apparently being very beautiful. He also carries around a Puyo-themed kendama.

His normal attire is a white shirt with a purple tie, grey jeans, a watch on his left wrist, and violet shoes.

He's rather strange and sarcastic, often talking in a smooth talking manner and generally being level headed. Though normally calm, he will start panicking if things go wrong. He is something of a gamer, disclosing his concerns about tabletop gaming to Risukuma in Puyo Puyo!! 20th Anniversary. A recurring quirk with his speech is that he tends to end his sentences with a star.

He is skilled with using his kendama as an improvised weapon. His spells reference this gimmick, and include Swing In, Lightning Drop, Moon Circle, Earth Turn, Backhand Slip Grip Special, Butterfly Dance, and Sidewinder, all of which are kendama tricks. Puyo Puyo!! 20th Anniversary reveals that his eyes are apparently so beautiful they can make anyone, regardless of gender or species, fall in love with him, dubbed by Ringo as the "Beauty Beam".

He has two best friends. Ringo Ando, who is a girl with red spiral pigtails, a puyo hairclip, yellow vest, red skirt, red boots, and purple stockings. She's analytical and logic-headed, having a love for math and apples but a hatred for ghosts. Meanwhile, Risukuma, a bear/squirrel hybrid with a blue shirt, white lab coat, mauve jeans, and no shoes, is the leader of the physics club and enjoys experimenting on making love potions and experiments.

Maguro, Risukuma, and Ringo often have to deal with an otherworldly shadowy figure named Ecolo, who has a cyan smile, cyan eyes, and a cyan, diamond-shaped core. Ecolo tends to mimic others and often loves causing chaos and pranking the three. Ecolo has a very lax and careless personality, often laughing 'Wahaha!' and seeing Maguro and his friends (and to be frank everything else) as nothing more than toys.
