保科 啓

主人公与彩香的弟弟，保科家三兄弟的末弟。 他们是父亲再婚的后妻带来的孩子，与上面的两人是没有血缘关系的兄弟。和主人公在同一个学园上学。 与给人锐利印象的姐姐和哥哥不同，他继承了温和母亲的血统，性格平易近人。 外表上看起来完全不像实际年龄，加上天然的性格，经常被周围的人（特别是女生）捉弄。

The protagonist's classmate and Ayaka's younger brother, the youngest of the three Hoshina siblings. He is the step brother of the two older siblings, his mother remarried and is the second wife of the father of the protagonist and Ayaka. He attends the same academy as the protagonist. Unlike his sharp-looking older sister and brother, he inherited his gentle mother's traits and has an affable personality. He looks much younger than his actual age, and combined with his airheaded nature, he is often teased by those around him (especially girls). [From Getchu]

主人公と彩香の弟で、保科家三人兄弟の末弟。 彼らの父が再婚した後妻の連れ子で、上のふたりとは血の繋がらない兄弟。主人公と同じ学園に通っている。 シャープな印象の○い姉や兄と違って、穏やかな母の血を引いて人懐っこい性格。 外見的にもとても実年齢には見えない上、天然な性格もあいまって周囲（特に女子）からは、よくイジられている。
