汐山宏人

主人公同专业的朋友。 性格直爽，经常和主人公聊些无聊的话题聊得热火朝天。 汐山涼音的弟弟。 姐弟关系虽然不差，但因为至今为止一直被姐姐大肆滥用权力，所以不擅长应付涼音。

The protagonist's university buddy who's in the same major program as he is. He's a very social person, and he and the protagonist often joke and laugh around about dumb things. He is also the younger brother of Suzune. While they get along just fine, he's a bit scared of her due to her exerting her authority as the older one over him for many years. [Translated from the official website]
