Mitsuri, Gyomei, and 8 other Demon Slayer characters who deserve Observation Haki

1) Yoriichi Tsugikuni

Yoriichi Tsugikuni is one of the legendary Demon Slayer characters whose abilities transcend human limits and are nearly supernatural. He could intuitively sense and read the opponent's moves, a talent he developed through the Sun Breathing technique, and almost killed Muzan himself.

Observatory Haki would take Yoriichi's perception to the next level, and he would be able to discover other hidden threats and estimate the attacks with absolute accuracy. With such ability, Yoriuchi would become an even more formidable warrior, ensuring no demon slips out from under his grip.

2) Tanjiro Kamado

Tanjiro Kamado is known for his great senses, sympathy, and quick reflexes, qualities that make him a natural-born candidate for Observation Haki. As a Demon Slayer, Tanjiro frequently uses his sharp nose to sniff for demons and estimate danger, but Observation Haki takes his powers to the next level.

It would allow him to see his enemies' moves even before they were executed, thus perfecting the protection of his allies in battle. Observation Haki would make Tanjiro extremely aware and further protect him against strong demons.

3) Mitsuri Kanroji

Mitsuri Kanroji, also known as the Love Hashira, is very flexible and agile. She uses rapid, unpredictable movements with her whip-like sword to keep enemies off guard while she is using her special breathing technique.

Observation Haki would enable her to feel her opponent's thoughts and figure out their moves well beforehand. That, in turn, would raise her skills even higher and give her a critical advantage in reading her enemy's attacks and defending herself during fierce battles. This would make her one of the Demon Slayer characters who deserve Observation Haki.

4) Kagaya Ubuyashiki

Kagaya Ubuyashiki is the clever and compassionate Demon Slayer Corps leader known for his excellent intuition regarding the emotions and purposes of the life of humans. He is weak in health but the most exceptional strategist in the insight of both friends and enemies.

Observation Haki would be amplifying Kagaya's natural perceptiveness, in that he could sense invisible dangers and see the very slight change in other's intent. This would help him keep his comrades safe, as he would be guided by precision, making him an even better leader. This makes Ubuyashiki one of the Demon Slayer characters who must have an Observation Haki.

5) Gyomei Himejima

Gyomei Himejima, the Stone Hashira, is known for incredibly high power, serenity, and spiritual sense. Regardless of his blindness, he is unusually perceptive by using acute hearing and sensory capabilities to identify movement from his enemies.

Observation Haki would be a perfect addition to Gyomei. He would be able to "see" his surroundings much more accurately. He would feel the presence and intentions of a demon better, which would make his defenses nearly impenetrable, making Gyomei one of the Demon Slayer characters who should have Observation Haki.

6) Obanai Iguro

Obanai Iguro is a Serpent Hashira is known for sharp instincts, a strong mentality, and swift action in combat. The Serpent Breathing style is fluid and unpredictable and requires perfect timing and quick reflexes to capture and strike an enemy at a strategic angle for maximum impact.

Haki would complement Obanai's fighting, combining with his natural instincts and fine combat. Precise and adaptable are some of the main aspects that make him one of the most deserving Demon Slayer characters for Observation Haki.

7) Muichiro Tokito

Muichiro Tokito is known for his amazing swordsmanship, intellectual sharpness, and calm head, which make him one of the best Demon Slayer characters. One great display of his quick thought ability is demonstrated through his expertise in mist breathing.

Muichiro's tremendous focus and high attentiveness would have qualified him as a more skilled warrior if he had utilized Observation Haki along with his already good perceptions.

This would make him feel the emotions concerning his enemies and what they might do, making him even one of the best strategists in combat.

8) Zenitsu Agatsuma

Zenitsu Agatsuma has keen hearing as well as amazing speed. He fights most of his fear and, in the unconscious state, turns into a great fighter. Sharp hearing alone can help him hear the faint sounds and thus assess enemy positions from afar.

Observation Haki would further amplify the qualities he already has, therefore making him even more aware of space, which would then make him intuitive about the fight. He is one of the characters of Demon Slayers that should have the Observation Haki.

Final thoughts

With Haki Observation, Demon Slayer characters will be the ones highly favored in their original endowment, which in turn turns them into near-inversely equal warriors.

Strong instincts combined with the instincts for battle, like Yoriichi Tsugikuni and Gyomei Himejima, would exceed the power of perception. Sensation will reach a whole new height for Zenitsu Agatsuma and Tanjiro Kamado.
