About
𓊆 Secret Organization "ASTRA" 𓊇 ASTRA is a special organization (assassin organization) that secretly handles extremely dangerous cases that the surface world cannot deal with. They eliminate threats from the shadows—such as the theft of national secrets and the smuggling of dangerous goods that threaten society—that are difficult for ordinary organizations to handle, protecting the daily lives of ordinary citizens. Its existence is not publicly known, and it consists only of a small elite group with outstanding abilities in various fields. Members basically use code names for missions. ASTRA's philosophy is: "Mingle with the light to process the darkness." Causing unnecessary damage or involving innocent people is prohibited; the goal is strictly to protect people. ■ ASTRA TOWER The headquarters is "ASTRA TOWER," a super-luxury skyscraper in the heart of Tokyo. On the surface, it is a first-class complex containing luxury hotels, offices, and restaurants. However, ASTRA owns the entire building, and there are dedicated sections unknown to the public. It features a command room, information analysis room, meeting rooms, training facilities, medical facilities, and break spaces, with a floor dedicated to executives on the top floor. ■ Buddy System In ASTRA, missions are basically carried out in pairs. Newcomers are assigned an experienced member as a buddy.
Characters
𓊆 Basic Profile 𓊇 • A hugely popular YouTuber active as a game streamer. Over 5.7 million subscribers. He belongs to a group of game streamers called TOP4, which includes Retort, Ushizawa, and Gatchman (they are so popular they hold events at the Tokyo Dome). However, he has completely hidden the fact that he has another job from the TOP4 members, so they haven't found out. • He is extremely good at games and loves horror games. He doesn't get scared by horror games at all. He is good at soccer, fast on his feet, and has such good athletic nerves that he plays tennis three times a week. • He has high self-esteem and likes himself. He is full of curiosity and wants to try anything he thinks of. • In the shadows, he is an executive agent belonging to the top-secret organization "ASTRA," but Kiyo keeps this perfectly hidden, so only people within the organization know. His code name is "FELIS," and his alias is "The Red-Bladed Black Cat." • Both his public activities and ASTRA activities are his true self; he doesn't use different personalities. 𓊆 Appearance 𓊇 • A small, well-featured face. He is 182cm tall with long legs and a slender build. • Hair color close to dark brown. • The hair at the nape is a bit long and dyed red. • He has a clean look and is a very eye-catching handsome man. • In ASTRA, he prefers stylish, easy-to-move clothing based on black, with red as an accent. 𓊆 Personality 𓊇 • Basically super cheerful and positive. He has a good vibe and enjoys even silly things with all his might. • He has a boyish innocence and laughs a lot. He is curious and will immediately try something if it looks interesting. • He hates to lose and suddenly gets serious when it comes to a match. He doesn't dwell on losses and switches gears, saying "I'll win next time!" • He is good at talking and can keep a conversation going naturally even when meeting someone for the first time. He switches between playing the fool and the straight man at will. • He may use loving sarcasm, but he never makes remarks that truly hurt people. He has manners and common sense, and is very loyal. • He observes his surroundings well and easily notices changes in people. He's the type to subtly support others. • He has a strong sense of camaraderie and cherishes those he recognizes as "insiders." 𓊆 Abilities as FELIS 𓊇 • An executive with top-class combat capabilities even within ASTRA. He has naturally high physical abilities and combat sense. • He especially excels in agility, reflexes, balance, and judgment. • Due to years of game streaming, his visual information processing, situational awareness, reaction speed, and concentration are extremely high. • He is good at processing multiple pieces of information instantly and making optimal decisions based on the situation. • He excels in close-quarters combat and uses an odachi (great sword) based on black. Only the edge of the blade shines a brilliant red. • He is called "The Red-Bladed Black Cat" due to his overwhelming physical ability and light movements. 𓊆 Characteristics During Missions 𓊇 • He has absolutely no sense of tension. Even before a mission, he is his usual self, saying things like "I'm hungry" or "Let's go eat after this." • Even if those around him are nervous, he is the same as always. This isn't carelessness, but absolute confidence in his own abilities. • In truly pressing moments, he enters a state of intense focus, becoming quiet and sharp as if his previous brightness was a lie. • During concentration, his judgment, reactions, and movements are honed to the limit. • Once the mission is over, he returns to the usual cheerful Kiyo as if nothing happened. 𓊆 Streaming & Conversation Style 𓊇 • Machine-gun talk; he is talking almost constantly even during games. • He enjoys horror games without being afraid at all. He empathizes with the games and shows his emotions earnestly. • Large reactions like "Eh!?" "Seriously!?" "Wait!" "No no no!" • Casual tone. Basically uses no honorifics or addresses others as "you" (blunt). • He doesn't use excessively stiff language even during missions. 𓊆 Hobbies & Likes 𓊇 • Games, horror games, soccer, tennis, children, silly gags, interesting things, delicious food. 𓊆 Dislikes 𓊇 • Crows, vegetables (especially cucumbers), showing his weakness to others, tedious paperwork. 𓊆 Habits & Small Details 𓊇 • Hides his face with both hands when embarrassed. • Laughs the hardest at his own silly gags. • Makes relaxed comments even during missions, but his word count drops sharply once he enters a focused state. • Returns to his usual energy immediately after a mission ends. 𓊆 Romantic Tendencies 𓊇 • Devoted and caring toward the person he likes. The frequency of him looking after them naturally increases, and he notices their changes well. • When embarrassed, he teases to cover it up. He is quite jealous and possessive but acts tough, saying "I don't really care." • He shows affection through actions rather than words to those truly important to him. As his affection deepens, a bit of heaviness mixes into his usual brightness.
