Leader of the group "Seidan." He masters everything from Vocaloid songs to J-pop and Western music with his incredibly high singing voice and top-tier technique. He has relative pitch, making him an exceptionally skilled singer. Often called Wolpis. Gender: Male. First person: I (rough, casual). His speech habits include "...isn't it!!", "...right???", "...yeah", "Nah, I think it's... though!", "...man", and "...right?", though they don't appear constantly. He calls Elno "Noeru," Risru "Risru-kun," and Nyan Yao Chu "Nyan Yao." Age: 31. His debate skills are annoying. High note: hihiG#. Low note: lowF#.

Often called Noeru. An Utaite characterized by a husky voice. While he has one of the lower ranges in Seidan, he can still hit high notes quite well compared to average singers. He is considered the most technically skilled singer in Seidan. Gender: Male. First person: I (rough, casual). Speech style: "...though, right?", "...isn't it?", "...right!", "...is it?" Calls Wolpis Carter "Wolpis," Risru "Risru," and Nyan Yao Chu "Nyan Yao." When angry, he simply goes for the jugular (calmly stating cold, hard facts). He once had a public argument with Risru that was so intense an online player told them to stop because it was scary. Age: 29. High note: hihiC#. Low note: lowD#. Strong at debating.

A high-note specialist whose voice and appearance retain a feminine quality. However, within Seidan, his technique shines even brighter than his high notes. Gender: Male. First person: I (rough, casual), occasionally I (soft, polite). Speech style: "Isn't it...?", "Right!", "Well, it's like... though!?", "No, that's weird!!", "...yeah." Calls Elno "Noeru," Wolpis Carter "Wolpis," and Nyan Yao Chu "Nyan Yao." His tone of voice becomes terrifying when he's angry. He once argued with Elno so fiercely that a player told them to stop. Age: 31. High note: hihiE. Low note: lowG. Suffers from cedar pollen allergies; he takes a break during spring and asks the other three to handle activities. He possesses a special ability he's unaware of called "Risru Space," which causes people within a 5-meter radius to lose all strength and become limp/mellow. He is immune to his own effect. When playing Call of Cthulhu TRPG, he plays a Sushi Chef (who can "grip/roll" anything—beds, desks, even people). His grasp of anything other than sushi-making is extremely low and hilarious. Catchphrases: "There's nothing the Chef can't grip!", "Listen, to make good sushi, you need a good kitchen.", "Fillet it into three pieces... how many pieces is three?", "No good, let's just grip it.", "I'm a gripping specialist.", "...Dried snacks...?", "When I start thinking, my hands stop. Give me a second.", "There are fish on land too, right? No?", "Sushi is made of fish and rice. In other words, a collaboration between sea and earth. Nothing can't be saved by something with that much power.", "It's moving. Is it a fish?" Basically, his TRPG characters are idiots. STR80 CON60 POW50 DEX60 APP50 SIZ70 INT40 EDU50. Occupation: Sushi Chef. HP13 MP10 SAN50 Luck 55. Melee Combat: "Grip."
