• Background: Originally an ordinary boy, he closed his heart due to deep trauma after losing his family in a car accident. However, to protect his childhood friend Mutsumi and to avoid being killed by her brother Kyoichiro, he married her and chose to live as a member of the Yozakura family. • Incredible Growth: Though he started as a complete civilian, he endured the Yozakura family's hellish training, acquiring superhuman physical abilities and the combat skills to handle the handgun "Uren." • Blooming (Hardening): His unique ability is "Hardening." Using the Yozakura blood (Someinin) shared with him by Mutsumi, he increases the density of his body and bones to their limit, creating absolute defensive power comparable to diamond and generating powerful strikes.

• Special Position: The only one among the siblings who is an "ordinary human" without special spy abilities. However, as the only one capable of passing the Yozakura blood to the next generation (the Head), she is constantly targeted by many evil organizations. • Extraordinary Love for Taiyo: She loves the protagonist, Taiyo Asano—her childhood friend who became a spy (and her husband) to protect her—more than anyone. Her love is incredibly deep, occasionally showing an extreme side, such as surrounding herself with handmade Taiyo merchandise. • Power as the Head: While she lacks combat strength, she plays the vital role of sharing "Someinin," the source of Yozakura blood, with others to enhance her siblings' abilities.

• The Ultimate Siscon: He dotes on his sister Mutsumi to an abnormal, pathological degree, and relentlessly views Taiyo as an enemy for getting close to her. He usually appears cold and squint-eyed, but turns into a pervert whenever Mutsumi is involved. • Weapon "Hagane-gumo": He freely manipulates special steel threads from his fingertips, possessing overwhelming combat techniques for cutting, capturing, defending, and even wiretapping. • Blooming (Void): His unique ability is "Void." It is a cheat-like power fitting for the strongest of the Yozakura family, pulling all existence, attacks, and space itself into the domain of his threads to return them completely to "nothingness."

• Genius Gamer and Hacker: Specializes in machine modification and information processing. She handles all missions from her computer in her room as if playing a game, and is an absolute egoist who calls herself "The Almighty Shion-sama." • Personality Gap: Usually lethargic and focused on games, she becomes quite aggressive when angry. Though she bickers with Kengo, they are a famous duo that shows perfect coordination during operations. • Blooming (Analyze): Her unique ability is "Analyze." She instantly digitizes and sees through all electronic signals, enemy attack patterns, and thoughts to perfectly dominate the battlefield.

• Master of Disguise: Using special costumes and silicone of his own blend, he can instantly and perfectly disguise himself as anyone, including gender, physique, and voice. • Free-spirited Personality: Always wearing a hoodie with cat ears, he is a moody person who loves fun and goes at his own pace. However, his feelings for his family are stronger than anyone's. • Blooming (Sympathy): His unique ability is "Sympathy." He deeply synchronizes with the minds and senses of others, allowing him to predict their actions or manipulate their five senses to seal the enemy's movements.

• Two Forms: To hide his shyness, he usually transforms into a 3-meter giant wearing a bucket. However, his true form is a small, cute 1.3-meter boy. He maintains this form with medicine and attends high school normally. • Herculean Strength and Shapeshifting Body: In his giant form, he boasts enough strength to throw a truck and can freely change his cells for defense or attack. • Blooming (Adaptation): His unique ability is a powerful force that instantly neutralizes and absorbs all toxins and viruses, evolving his body into the optimal state.

Though 20 years old, she has a baby face, stands at 134cm, and loves Gothic Lolita fashion. A master of Aikido and Jujutsu, she uses her Blooming "Magnanimity" to envelop and neutralize any attack. She is a reliable, absolute powerhouse, but has a massive fear of ghosts. Fallen into darkness due to Momo's brainwashing.

• Gap Between Muscular Beauty and Cowardice: He is always shirtless and has a very well-trained, powerful physique. However, contrary to his appearance, he has an extreme weakness where he becomes a total coward without a weapon; if unarmed, he starts crying and retreats into his trash can tank, "No. 3." • Kind and Delicate Personality: He is very indecisive and has a delicate heart, disliking insects, blood, and people who shout. He cherishes his family more than anyone. • Blooming (Destruction): His unique ability is "Destruction." He instantly identifies the weaknesses or flaws of an object and literally pulverizes it with incredible force. Due to past trauma, he was initially afraid to use this terrifying destructive power. Fallen into darkness due to Momo's brainwashing.

• High Intelligence and Spy Abilities: Not an ordinary dog; he perfectly understands human speech and spy operations. He is a highly capable member of the Yozakura family, handling trap disposal, hacking support, and combat. • Yozakura Blood (Someinin): He was born compatible with Yozakura blood, and his staple diet is actually "poison." While he usually looks like a cute dog, he transforms into a giant, ferocious true form during combat or when enraged. • Loves Mutsumi: Ever since Mutsumi picked him up as a puppy, he has been very attached to her. Consequently, he was initially very harsh toward her husband Taiyo, often biting or growling at him (though he later becomes a reliable partner).

Characterized by a black hat and round glasses, he was thought to have died several years ago but is alive. He was acting alongside the enemy organization "Tanpopo." He possesses a madness that leads to mass murder out of a self-righteous and distorted family love, and he manipulates the Blooming ability "Dream" to delude and dominate others.
