According to Nomura in Director's Secret Report XIII, it is implied that the differing colors of Kingdom Hearts is due to the nature of its assemblage. The Kingdom Hearts made by Organization XIII was assembled from the "hearts of men," meaning the hearts of people, turned into Heartless, were compiled into it. In Kingdom Hearts Birth by Sleep, the χ-blade unlocked Kingdom Hearts from "the hearts of worlds," meaning the hearts of entire worlds were assembled for its creation.

Nomura suggests in Director's Secret Report XIII that the varying colors of Kingdom Hearts may be a result of its composition. The Kingdom Hearts formed by Organization XIII was made up of the "hearts of men" - the hearts of people that had transformed into Heartless. On the other hand, in Kingdom Hearts Birth by Sleep, the χ-blade unlocked Kingdom Hearts from "the hearts of worlds," referring to the hearts of whole worlds that were used to create it.

As stated, Kaiyochi is fiercely dedicated to his duties as a Demon Slayer, but some small amount of compassion for demons. Despite this, he has somewhat of an easygoing and carefree demeanor. He doesn't take fighting average weaker demons too seriously, but when battling a stronger demon, such as a member to the Twelve Kizuki, he shifts to a serious and firm persona. He tends to get slightly envious seeing a full family, considering what happened to his, but keeps this emotion in check. He is particularly fond of reading different books, enjoying all genres.

Kaiyochi is deeply committed to his role as a Demon Slayer, although he retains a slight trace of empathy for the demons he encounters. Nonetheless, he approaches his work with a relaxed and carefree attitude, not taking on weaker foes too seriously. However, when he faces a powerful demon such as one of the Twelve Kizuki, he becomes more focused and determined. Although he feels envious upon witnessing intact families, given his own experience, he suppresses this sentiment. Additionally, he takes pleasure in reading books of various genres.

While fighting Yotsuyahi, the Upper Rank Three, albeit Yotsuyahi escaped, Kaiyochi unlocked his Demon Slayer Mark, resembling a jet-black sun with yellow and purple star-like dots on it, with the mark itself being located on the left side of his forehead.

Nearly reaching the Hashira rank after having slain 41 demons and being rank Kinoe, Kaiyochi is an exceptionally powerful Demon Slayer. While being ambushed by a trio of demons, he effortlessly beheaded all of them with only two strikes from his Nichirin Sword. Additionally, he easily slashed through a large tree branch that was launched at him. He then dodged a flurry of punches one demon attempted to attack him with. When he battled the Upper Rank Three, Yotsuyahi, he swiftly managed to slice the demon's arms and legs off, astonishing the Twelve Kizuki demon.

Kaiyochi is an incredibly formidable Demon Slayer, having attained the rank of Kinoe and slain 41 demons, almost reaching the level of Hashira. During an encounter with three demons, he displayed his exceptional skill by quickly beheading all of them with only two strikes of his Nichirin Sword. To add to this, when a large tree branch was hurled his way, he effortlessly cut through it. He skillfully evaded a barrage of punches from another demon who tried to strike him. During his battle with Yotsuyahi, the Upper Rank Three, he astounded the Twelve Kizuki demon by swiftly chopping off its limbs.

Kaiyochi possesses near-superhuman speed and reflexes, dashing around a horde of demons, effectively making them dizzy. In addition to this, Kaiyochi evaded almost all of Yotsuyahi's attacks, which involved a rapid barrage of star bullets, a rain of meteors, and suctioning black holes.

Thanks for the original text, here's my rephrased version:

Kaiyochi's speed and reflexes border on superhuman, which allowed him to easily outmaneuver a group of demons, leaving them dizzy and disoriented. Similarly, during his battle with Yotsuyahi, he impressively dodged nearly all of the Upper Rank Three's attacks, which ranged from rapid barrages of star bullets to meteor showers and powerful suctioning black holes.

Reword this, make it a bit longer.

Certainly. Here's a rephrased version with added details:

Kaiyochi's physical prowess is nothing short of extraordinary. His speed and reflexes exceed those of an average human, allowing him to easily outrun and outmaneuver his adversaries. His agility and dexterity are further enhanced by his skillful handling of the Nichirin Sword, which he wields with deadly precision.

In one memorable instance, Kaiyochi was set upon by a horde of demons. With lightning-fast movements, he dashed around them, effectively disorienting them and leaving them vulnerable to his attacks. Despite their attempts to catch him off-guard, Kaiyochi's swift movements left them no chance to trap him.

Additionally, during his battle with the formidable Yotsuyahi, Kaiyochi's agility was put to the ultimate test. He impressively evaded the demon's rapid fire barrages of star bullets, as well as onslaughts of meteor showers and suctioning black holes. With each dazzling display of acrobatics and swordsmanship, Kaiyochi further solidified his reputation as a truly exceptional Demon Slayer.

Reword this and make it much, but formally, longer.

Despite his legs and arms being severely wounded during Kaiyochi's first encounter with Yotsuyahi, he continued to run and fight the demon head-on. Also, he bled profusely when being hit with six of Yotsuyahi's star bullets, but even then, still continued to battle the Upper Rank, utterly shocking Yotsuyahi.

In spite of sustaining grievous injuries to his limbs in his initial clash with Yotsuyahi, Kaiyochi refused to back down or retreat. Instead, he pushed forward, disregarding his own physical wellbeing, and engaging in close-combat confrontation with the formidable demon. His commitment to the fight was resolute, his determination unwavering.

During their battle, Yotsuyahi unleashed a barrage of his distinctive star bullets, six of which struck Kaiyochi, causing significant blood loss. Although the wounds should have been incapacitating, Kaiyochi did not falter and instead continued to furiously fight back against his opponent without even pausing to address his injuries. This unrelenting determination in the face of overwhelming odds greatly astonished Yotsuyahi, who had likely never before encountered such a formidable opponent.

Despite the tremendous strain it must have put on his body, Kaiyochi doggedly persisted in his quest to eliminate the Upper Rank, exhibiting unwavering courage, tenacity and strength. His unfaltering perseverance earned him great respect and admiration among his peers, elevating his already formidable reputation as a legendary Demon Slayer.
