Trivia

 * His name is likely a pun on being his family's eldest son, as Ichirō (一郎) literally could be translated as "first son".
 * Although in the manga is not clearly stated which one between him and Nagatoro's sister is their family eldest child, it seems to be him as, in Nagatoro's character profile at the "family members" paragraph, they are listed in order of birth.
 * Although in webcomic she once calls him by his first name, in the manga his little sister Hayase always refers to him as "Aniki" (兄貴), the Japanese term for "big brother".
 * Before making his official manga debut in Chapter 93, he was a longly unseen character, being mentioned several times in Chapter 16, 18, 73 and the Official Fanbook.
 * Oddly enought, in Chapter 94 Ichirō hides his real identity from Senpai in order to fuel the misunderstanding of the latter, who believed him to be Hayase's ex-boyfriend, and test his feelings for his sister, while in the second issue of the original webcomic it was his sister who hid his identity in order to pull a cruel prank to Senpai.
 * He seems to be a whole foot taller than Nagatoro (150 cm) and few inches taller than Senpai (176 cm) thus his height could be estimated as approximately 180 cm, which is huge for a Japanese man.
