Yohei Kanbayashi, known as God Summer, is a 28-year-old Japanese rapper and bartender. He has fair skin, dark blue middle-parted hair, amber eyes, and a distinctive mole beneath the left side of his mouth. His style features multiple accessories including chains, bracelets, ear piercings, and a left-hand tattoo. He favors practical yet stylized clothing like floral shirts, leather biker jackets, and brogues, with stage outfits incorporating more elaborate designs such as studded varsity jackets. Born August 28, he joined the Suiseki gang at 15 after junior high. By 17, he met Naoakira Saimon, left the gang for rapping, and formed the unit "XXXX" (Quadra X) with Saimon and Saimon's wife, Tsubaki. The unit disbanded when he was 19, leading him to become barmaster of Bar 4/7. He resumed rapping at 22. Hashtags like #TheFlowerILovedDiedWithoutKnowing and #ColdPiano reference his unresolved grief and guilt over Tsubaki's death. His nocturnal routine centers on Bar 4/7 operations from 12 AM to 4 AM, followed by social drinking elsewhere until 7 AM. He prepares meals for Ryu Natsume and Shiki Ando, sleeps from 8:30 AM to 4 PM, and preps the bar in the evening, reflecting his commitment to profession and found family. Blunt and quick-tempered due to heavy drinking, he retains past roughness but shows genuine compassion and reliability. He treasures hip-hop's spirit and a "man among men" ethos prioritizing protection and loyalty. Key relationships include his long-term friendship with Naoakira Saimon, rooted in shared music history and co-managing Bar 4/7. He provides daily meals and care for Ryu Natsume, who calls him "Master," and supports Shiki Ando. Ties to Suiseki persist through familiar interactions with Iori Suiseki and respectful exchanges with Zen Gaho. As part of The Cat's Whiskers, he participates in "Phantom Live" battles using his Phantometal—a skull-shaped cigarette holder with blue-stone eyesockets. Activating it requires lighting a cigarette, generating illusions tied to his performance emotions. He states whiskey as his favorite food, dislikes whipped cream, and enjoys cocktail-making. He struggles with technology and spends free time drinking. His future dream is protecting Bar 4/7, underscoring dedication to stability and chosen family.
