Backstroke swimmer of the Iwatobi High School swimming team.
Makoto Tachibana is Haruka’s inseparable best friend in 11th grade. He understands Haruka’s good points, and is often forced to speak as his spokesman. He is very kind and considerate, but is also very easily scared and weak-hearted.
He is afraid of the ocean due to an incident that occurred when he was in elementary school. A typhoon resulted in a ship crew drowning just about 3 km from the harbor. The crew included an old fisherman who was Makoto’s friend.
