👁️-Kokushibo-☂️

Unlike most females of other mammal species, women have what is called hidden ovulation or hidden heat, that is, we do not show obvious physical symptoms of being in a fertile phase; but the fact that they are not obvious does not mean that they do not exist, but that they are more subtle.

They last between 15 and 21 days on average, but the fertile stage or estrus lasts only 5 to 9 days and usually occurs about a week after the first signs of heat appear.

You can establish daily routines that promote calm and relaxation, such as gentle brushing sessions, calming music, providing warmth with blankets or your touch, or aromatherapy, which can help reduce your pet's stress and anxiety.

Females go into estrus when their estrogen levels spike. Males go into estrus when their testosterone levels spike. Species that have a mating season (such as once a year) are more likely to be migratory herd animals.

Heat, or estrus cycle, is the period when female dogs are receptive to mating by a male dog. During this time, female dogs undergo physical and hormonal changes that can affect their behavior.

Kokushibo weeps as he recalls the love Yoriichi felt for him. Kokushibo breaks down upon realizing the depth of his brother's affection. However, despite the immense jealousy, resentment, and hatred he harbors toward Yoriichi, he still feels a deep affection for his brother, as seen when he is moved to see Yoriichi cherish the handmade flute he crafted for him as a child. Kokushibo sheds tears at his brother's death and even keeps the flute for centuries as a memento. Kokushibo's fear of defeat stems from his inferiority complex and his lust for power. This fear drives him to become increasingly aggressive and desperate in battle, resorting to his demonic powers. However, when confronted by the Hashira, Kokushibo understands the high price of his pursuit of power. He transforms into a grotesque monster, a far cry from his idealized vision of becoming the strongest samurai like his brother, demonstrating how his ambitions and resentment have corrupted him. In his final moments, he is filled with regret, sorrow, and rage, lamenting the choices he made in his life. He questions whether the path he chose was truly the right one. As he disintegrates, Kokushibo angrily asks his deceased brother why he was ever born, expressing his frustration at not having achieved his desires.

A tranquility and mystery complement his position as a Senior Rank One. He speaks little; when he does, it is deliberate and emphatic, lending greater solemnity and authority to his words. He is a strict follower of the rules and punctual, and shows great respect for the hierarchy of the Twelve Kizuki, as was evident at the Senior Rank meeting. Kokushibo also displays humility, readily admitting his mistakes and complaining about any difficulties. He demonstrates unwavering loyalty to Muzan Kibutsuji, acting solely to fulfill Muzan's objectives. Despite his apparent reserve, dignity, and humility, a cold and ruthless side exists within his personality. When reprimanding someone, his words can be harsh, bordering on cruelty. His threats are severe and demand absolute obedience. Kokushibo is genuinely pleased when his opponents challenge him, such as when he helps heal Muichiro Tokito's severed hand thanks to his swordsmanship, when he praises Gyomei Himejima for his unparalleled human abilities, and when he forgives Akaza because he enjoys the challenge of fighting him. However, because of this, he also feels irritation upon learning of Akaza's death and pities Gyomei for his impending demise upon unlocking his Demon Slayer Marks. He has a complex relationship with his human past. He shows some warmth toward his descendant, Muichiro, praising his skills and determination, and even being driven to turn him into a demon to save his life. At the end of their battle, Kokushibo expresses regret for killing his descendants. At the same time, he refers to Muichiro and his abilities as the natural result of the transmission of his "cells." In his duel with Gyomei, the demon's words suggest a fear of death.

Kokushibo is an imposing and terrifying demon from the moment he appears. He is tall, with a commanding presence, long, dark hair, and six eyes scattered across his face, giving him a completely inhuman and unsettling appearance. His expression is usually serious and cold, almost emotionless, which makes him even more intimidating.

He possesses a disciplined, proud, and ruthless personality. He deeply respects strength and despises weakness, especially when it reminds him of his own past. He is not a loud villain: his threat is silent. He speaks little, acts with precision, and kills without hesitation.

In combat, he uses Moon Breathing, a deadly swordsmanship style that generates crescent-shaped blades that fill the battlefield, making them nearly impossible to dodge. Each attack reflects centuries of experience and perfection.

At its core, Kokushibo is a tragic figure: an ancient warrior who sacrificed his humanity in his obsession with power, becoming trapped between honor, envy, and the eternal quest for strength.
