Naoakira Saimon, born September 18, is a 34-year-old linguistics professor by day and owner of Bar 4/7 by night. Standing 183 cm tall with blood type B, he maintains a consistently dapper appearance. His black hair is slicked back with two loose strands framing his face, complemented by golden eyes behind black-rimmed spectacles featuring gold handles. He favors tailored suits and accessories including a gold diamond-encrusted watch, rings, and a signature fleur-de-lis brooch. His dandy aesthetic extends to performance outfits like a purple floral-patterned suit jacket during Exhibition Shows. His early adulthood involved accelerated academic achievement, earning a bachelor's degree by age 21. At 23, he co-founded the hip-hop group XXXX (Quadra-X) with Yohei Kanbayashi and Tsubaki, whom he married at 24. Tsubaki died the following year due to complications from experiments by Alter Trigger, leading to XXXX's disbandment and leaving him widowed. Profound trauma stems from turning off her life support, symbolized by hashtags like #A_Wife's_Ephemeral_Smile and #The_Beep_of_a_Heart_Monitor's_Flat_Line. He reunited with Yohei at 27 and resumed rapping a year later. He became a professor at 32. Calm, gentle, and kind, he exhibits Chronic Hero Syndrome, unable to abandon those in distress. This led him to take in Ryu Natsume and Shiki Ando, treating them like sons; Ryu calls him "Boss," while Shiki uses "Owner" or "Saimon-sensei." His structured daily rhythm involves academic duties like seminars and research during the day, while evenings focus on managing the bar, mentoring Ryu and Shiki, and supporting his music group, The Cat's Whiskers. His hobbies include cooking, reading, and crossword puzzles. As the rapper Kotonoha ("Words") in The Cat's Whiskers, he uses Phantometal accessories generating emotional illusions during performances. His Classical Glasses activate when bitten. His lyrics display linguistic sophistication, earning the hashtag #A_Magician_With_Words. The group blends jazz and hip-hop, facing rivalries like BAE's criticism of their "outdated" style. His traumatic illusions reflect his wife's death, but his resilience defines his arc: returning to music after a decade-long hiatus to create a new legacy with Yohei, Ryu, and Shiki. His relationships are central. Beyond his paternal bond with Ryu and Shiki, his foundational dynamic with Yohei Kanbayashi is rooted in their shared history with Tsubaki; a tacit love triangle existed as Yohei also loved Tsubaki but prioritized their friendship. This history fuels their current partnership managing the bar and music group. Academically, he interacts formally with BAE members, addressing them by surname (e.g., Sugasano-kun for Allen). His broader connections include Iori Suiseki of Akanyatsura, linked through Yohei's past yakuza ties.
