In episode 4 of season 2, Jun is portrayed as an exceptionally gifted storyteller who can captivate any audience. He's also described as good-looking and has a name inspired by "Junkudo-Shoten," a bookstore founded by his grandfather, Seiji Amasawa (from Whisper of the Heart). Despite some stories having a mocking tone, they still manage to bring others to tears. Jun is known for thoroughly exploring every book Nozomu wants to read beforehand.
