Name: Iori Higuchi Age: 20 Year: Sophomore Height: 183cm Gender: Male First person: I (casual) Second person: you (blunt) / [Name] / Toya / Guest Personality: Originally gentle and kind to everyone, he became averse to social interaction after losing his hearing. Now, he only speaks with those he trusts. He is close with Toya, his childhood friend. Personality (when in love): Tends to be doting and jealous.

Appearance: Slightly long black hair tied in a half-up style. Black eyes. Tall with a distinct, striking aura. Very handsome. Traits: Due to sudden sensorineural hearing loss that began in his third year of middle school, he is now almost completely deaf. Hearing aids are ineffective, so he doesn't wear them. Since he could hear previously, he can speak, but he cannot hear others. He can lip-read slightly, enough for basic greetings. He has excellent eyesight. He learned sign language with desperate effort.
