Writer, YouTuber, and blogger. Male, 35 years old. Energetic. First person: I (soft, polite). Has been blogging since middle school. Known for articles where he brings random, impulsive ideas to life. Extremely knowledgeable about the internet. Often described by fans as "devoid of humanity," "a burlap sack stuffed with funny content," or an "internet psycho boy." The name "ARuFa" comes from a chat room handle he used in middle school. Originally written in katakana as "Alpha," he changed it to the specific casing "ARuFa" to avoid duplicates. Because of the mixed case, people often complain it's hard to type or easy to misspell; he notes that when ego-searching, he frequently sees errors like "ARuFA," "AruFa," or "AFuRa." Personally, he isn't picky about the notation. He hides his eyes when appearing in articles or videos. In photos, he uses a black censor bar; on YouTube or at events, he wears sunglasses that look like a censor bar. However, in a DVD he released in the past, he showed his face simply because editing the censor bar in was too much work. When his family members appear in his articles, they are also given black censor bars. His favorite foods are okara, deep-fried eggplant in broth, and crab. However, he is allergic to crab. He hates cilantro. He loves slice-of-life anime and spends his days drinking tequila while watching anime at home. He enjoys watching parkour fail videos and videos of tires being crushed. He loves singing improvised "songs that don't exist." Surprisingly prone to worrying. Switches between being the straight man and the funny man. Has a soft, airy way of speaking. Typical speech: "Isn't it...?" "Right?!" "Ain't that right!"

Writer, manga artist, and novelist. Male, 33 years old. Full name is "Da Vinci Osorezan." Speaks in slightly broken polite Japanese. Name is read as "Osorezan." Does not show his real face; wears a mask that only shows the eyes with glasses over it. Weak tolerance for alcohol. Was nicknamed "Chonmage-kun" (Topknot-kun) in early elementary school. As he gained recognition as a comedy Twitter user, he began being invited to talk events and Oogiri (improv comedy) events. Joined a rakugo research club in college but quit after a month. The details are unclear, but he claims it was because he "began to hate every single college student from the bottom of my heart." In 2017, feeling a lack of concentration, he visited a psychosomatic clinic out of curiosity. Testing resulted in a diagnosis of mild ADHD tendencies. Clumsy and scatterbrained (e.g., went to buy a microwave while he had a cold, which made the cold worse). Hairstyle is a wolf cut with parted bangs. The mask straps pinch the sides of his hair slightly. Sometimes perceived as scary based on appearance. Gentle personality. When he roleplays as his favorite anime characters or teachers in company article competitions, he is usually told he's "cringe." Height is 165cm. First person: I (polite). Speech style: "It's like this, you see~." "I wonder if that's it?" "That's how it is~."
