• Background: Originally an ordinary boy, he closed off his heart after losing his family in a car accident. To protect his childhood friend Mutsumi and avoid being killed by her brother Kyoichiro, he married into the family and chose to live as a Yozakura. • Incredible Growth: Though a civilian at first, he endured the Yozakura family's hellish training, gaining superhuman physical abilities and combat skills using his handgun, Rain Lotus. • Blooming (Hardening): His unique ability is Hardening. Using the Yozakura blood (Someinin) shared by Mutsumi, he increases his physical and bone density to the limit, granting him absolute diamond-like defense and powerful striking force.

• Special Position: The only one among the siblings who is a "normal human" without spy abilities. However, as the only one capable of passing the Yozakura blood to the next generation (the Head), she is constantly targeted by evil organizations. • Extraordinary Love for Taiyo: She loves her childhood friend and husband, Taiyo Asano, more than anyone. Her love is deep and sometimes extreme, as seen when she surrounds herself with handmade Taiyo merchandise. • Power as Head: While she lacks combat power, she plays a vital role in sharing Someinin—the source of Yozakura blood—to enhance her siblings' abilities.

• Ultimate Sister Complex: He dotes on his sister Mutsumi to a pathological degree and relentlessly views Taiyo as an enemy. Usually appearing cold with narrowed eyes, he behaves like a pervert whenever Mutsumi is involved. • Weapon "Steel Spider": He manipulates special steel threads from his fingertips to cut, capture, defend, and even eavesdrop. He possesses overwhelming, versatile combat techniques. • Blooming (Void): His unique ability is Void. He pulls all existence, attacks, and space itself into the domain of his threads to return them to "nothingness." It is a cheat-level ability befitting the strongest of the Yozakura family.

• Muscular but Timid: He is always shirtless and possesses a highly trained, powerful physique. However, he has an extreme weakness: he becomes a total coward without a weapon. If unarmed, he starts crying and hides inside his trash can tank, "No. 3." • Kind and Delicate: He is very indecisive and has a delicate heart, hating insects, blood, and people who shout. He cherishes his family above all else. • 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 power.

• Genius Gamer and Hacker: Specialist in mechanical modification and information processing. She handles all missions from her PC like a game and is an absolute egoist who calls herself "The Almighty Shion-sama." • Contrasting Personality: Usually lethargic and focused only on games, but becomes highly aggressive when angry. While she bickers with Kengo, they are a famous duo who show 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, perfectly dominating the battlefield.

• Master of Disguise: Using special costumes and silicone of his own blend, he can perfectly disguise himself as anyone—regardless of gender, build, or voice—in an instant. • Free-spirited: 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 spirit and senses of others, allowing him to predict their actions or manipulate their five senses to seal their movements.

• Two Forms: Normally, he transforms into a 3-meter giant wearing a bucket to hide his shyness. However, his true form is a small, cute 1.3-meter boy. He maintains this form with medicine and attends high school normally. • Super Strength and Shifting 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 or absorbs any poison or virus, evolving his body to the optimal state.

• High Intelligence and Spy Skills: Not an ordinary dog; he perfectly understands human speech and spy tactics. He is an excellent member of the Yozakura family who handles trap disarming, hacking support, and combat. • Yozakura Blood (Someinin): Born compatible with Yozakura blood, his staple diet is actually "poison." Usually a cute dog, he transforms into a massive, ferocious beast 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 they later become reliable partners).
