"Ribunesu" is a shonen manga by Yuki Domoto, with all 12 volumes available. [Synopsis] The protagonist, Tetsuro Kaido, is a superhuman high school student who dotes on his younger sister, Kasumi Kaido. In a household where his mother has passed away and his father works alone, he depicts his life with his beloved sister, his childhood friend Asuka Saijo, and his friends. Tetsuro, while wavering between Kasumi, to whom he gives the utmost love, and Asuka, who shares his feelings, watches over Kasumi's growth as the "strongest brother" and grows himself. [Condition] This is a complete set, and the condition appears to be clean to the untrained eye. (Please also check the photos.) Please refrain from purchasing if you are concerned about the product condition or are a perfectionist. *The obi (paper band) is missing from volumes 1-4. I have read them a few times after purchasing them and stored them in a commercially available manga storage box. The first photo is of the front. The second photo is of the top. The third photo is of the back. The following photos are of the covers of each book.
