Kirara

(pronounced as and occasionally spelled "Kilala") is Sango's faithful nekomata companion and main method of transportation. After the destruction of Naraku and the Sacred Jewel, Kirara became Kohaku's traveling partner and companion. In Hanyō no Yashahime, she serves as the partner of Sango's youngest child Hisui and also the half-demon demon slayer Setsuna.

History
Kirara is originally the companion of Midoriko, the miko who created the Shikon no Tama, suggesting that she is far older than she seemed, which made her the oldest member of Inuyasha's group. Sometime later, she became Shako's family companion, was passed down by Shako to Sango's father, and then by Sango's father to Sango when she was still very young.

During the story
When Kirara was first introduced, she was greeting Sango after she had come home from a mission. She was then seen playing with Sango right before she and the other yōkai taijiya went to Hitomi castle and were slain. Kirara helped fight to protect the demon slayer village during the attack, ending up as the only survivor. She was discovered by Myōga during this time, and joined Inuyasha's group on their search for Naraku's castle. During the search, Kirara reunited with Sango, who ordered her to kill Naraku if he did anything suspicious.

After these events, Kirara traveled with Inuyasha's group and acted as an ally and friend through the entire series. Kirara became fast friends with Shippō, often seen in his company when Sango wasn't around. When someone was depressed, Kirara often allowed them to rest on her for comfort.

When Kohaku was brought back to life by a Sacred Jewel shard, Kirara was ordered to kill Naraku to break the spell on him; however, she ended up badly poisoned by his miasma after biting his shoulder. She was later cured of the poison thanks to Jinenji's antidote.

Kirara was, at times, abused by Inuyasha, Kagome and Miroku for their own selfish needs; Inuyasha accidentally caused some of her fur to fall out, creating bald spots, while practicing the Wind Scar, Kagome used her for quick transport to the Bone-Eater's Well while forgetting promised cat treats to return the favor, and Miroku used Kirara to stage demon attacks to meet women. Despite this, she appeared to hold no grudge towards them, and the group felt deep regret for their past actions.

Kirara had many fond memories of her time living with Sango and Kohaku in the demon slayers' village. She met Kohaku during this time, and learned he was free of Naraku's spell. She heard Kohaku wishing that Sango could see the field of lilies near the village, so Kirara led her there.

Later life
Three years after Naraku's defeat, Kirara joined Kohaku as a traveling companion on his quest to become a more powerful demon slayer.

Personality
Since Kirara is a cat demon, she acted similar to regular cats: eating cat food, treats, fish, and playing with cat toys, as well as having cat-like weaknesses. Kirara was shown to be very intelligent as well as sentient. She is fiercely loyal to Sango, but with time, she showed loyalty to all members of the group.

Kirara demonstrated exceptional patience, often honoring the requests of the group and their various friends. For example, she allowed Inuyasha to practice the potentially lethal Kaze no Kizu attack on her, leaving bald spots on her fur. In addition, she helped Miroku impress village women and ward off the undesired advances of the older village women. Kagome admitted to playing dress up with her, and using her to return to the modern era without the knowledge of the rest of the group.

Physical description
Kirara usually appeared to be an adorable adult-sized feline (shown in the anime to be the same size as Kagome's cat, Buyo), but with the body proportions of a kitten. She has light yellow fur, black eyes with red sclera, black pointed ears, a diamond-shaped marking on her forehead, black paws with a stripe, and two fluffy tails with two stripes on each one. However, she had two forms: one of a cat, and a larger one resembling a. In her full-sized demon form, flames emerged from her feet and tails, and her power increased considerably, allowing her to battle even the strongest demon opponents.

Powers & Abilities

 * Kirara has the ability to transform from a small kitten to a larger cat that resembles a saber-toothed cat. When switching forms she is engulfed in flames, which, after disappearing, revealed the other form.
 * Pyrokinesis: Kirara can generate flame on her flanks and limbs after transformation. The unearthly fire doesn't quench underwater.
 * Fire Immunity: Fire and heat seem to do no harm to Kirara as she can act safe and sound when Renkotsu shelled and burned the valley.
 * Flight: When transformed, Kirara has the ability to fly and she was capable of carrying three grown adults at once, but she gets tired out quickly.
 * Prowess in Battle: Kirara is very powerful and experienced even in terms of demons. She lived through the situation to a degree that Midoriko (Kirara's former companion) probably the mightiest priestess, had to sacrifice herself (although her survival might very well rely on the latter's sacrifice). She is the only survivor after the battle of demon slayer village, which ended up killing all the residents and invading demons.
 * Enhanced Strength: When transformed, Kirara is very strong, several times managing to overpower many other foes, including larger demons.
 * Enhanced Speed: When transformed, Kirara's speed increased considerably. She is able to keep up with Entei and even with Inuyasha at top speed.
 * Enhanced Durability: When transformed, Kirara is very durable, managing to endure a practiced Kaze no Kizu from Inuyasha while he was practicing on her of her own free will, emerging fairly unscathed with only a part of her fur shaved off.
 * Enhanced Endurance: When transformed, Kirara could fight continuous battles against many foes for a considerable amount of time before tiring out, which makes her to transform back into her small kitten form.

Relationships
Kirara was with Sango and Kohaku's grandfather Shako, as he discovered the Shikon no Tama, until attacked by the Mistress Centipede as she rescued him. Also, he tells her to after the Ōmukade that she's getting away.

 * Sango

Due to their long past, Sango and Kirara were very loyal to one another and cared for each other greatly. They have always had a wonderful friendship and strong bond. Kirara often tried comforting Sango when she was sad, offering the comfort of her fur to ease Sango's pain. Since Miroku came into the picture, Kirara became fearful of Sango's anger. When, in Episode 97 Sango thought that she was killed by a gorilla demon, she immediately sought revenge and murdered him and remained in severe depression until learning Kirara was perfectly fine and cried tears of joy and hugged Kirara upon seeing her fine.

Kirara helped Inuyasha fight his enemies, and they often worked together. Sometimes, she acted as his "trusted steed", allowing Inuyasha to ride her into some fights with sword drawn. Inuyasha respected Kirara, knowing she was a reliable ally. She also allowed him to practice his Wind Scar on her despite the fact it caused her to have a few bald spots. He cares for her and when she needs medicine he heads to Jinenji's to get it in Chapter 112/Episode 32, stating he didn't mind since he saw her as a valuable ally and someone he could rely on during battle. In particular, it was their team up that helped Inuyasha kill Entei, which neither could have done alone.
 * Inuyasha

As her family owns their own cat, Kagome treated Kirara as her own, and sometimes Kirara helped Kagome fight demons. Kirara often got cat food and treats from the modern era as thanks from Kagome, which she enjoyed greatly. However, she was sometimes a victim of Kagome's dress-up games because of how cute her kitten form was. It also stated by Kagome that she has grabbed Kirara's paws and pinched her nose several times in Kirara's kitten form. Sometimes Kagome rode on Kirara's back as a means of transportation in order to travel back and forth between the modern and feudal eras.
 * Kagome Higurashi


 * Shippō

Kirara is particularly close to Shippō, who were often seen playing together. This was probably because of their shared connection of both being demons. Kirara is often seen with Shippō on her back when the others weren't riding her, most likely protecting him. It is also stated by Shippō that Kirara is his friend and he often sleeps on her back for her warmth. At times when Sango was frightening, Kirara and Shippō held each other.


 * Miroku

Miroku didn't seem to have much of a relationship with Kirara, although she did help him get the attention of some local village girls in one episode by pretending to attack a village, even scaring off old women interested in Miroku. She apparently didn't hold a grudge towards him for using her. Kirara often carried Miroku on her back along with Sango.

Having lived with Kohaku most of his life, Kirara was close to him as she is to Sango. However, their relationship was quite strained due to Kohaku being under Naraku's control most of the series. In an anime-only episode, Kirara met Kohaku once he had broken free of Naraku's spell, and fought demons alongside him in perfect combination. She honored Kohaku's desire to have Sango see a secret lily field, leading her there. During the three year time skip following Naraku's defeat, Kirara acted as Kohaku's partner in his quest to become a stronger demon slayer. Six months later, the two were still active together while dealing with a Root Head.

 * Hisui

The two often team up during missions with either Hisui or Towa joining them. Setsuna finds comfort in having Kirara with her as she often strokes the Nekomata's fur.
 * Setsuna

Towa referred to Kirara's ability to transform as amazing and the two often team up with Setsuna to handle demon slaying jobs. When the demon slayers were fighting Moroha and some bounty hunters, Towa hopped onto Kirara in order to aid Moroha who was outnumbered by the demon slayers.

Trivia

 * When Kirara enters water, the fire on her tail and legs do not go out.
 * In the anime, it was shown that Kirara had been in Sango and Kohaku's family for at least three generations, as she was seen accompanying their grandfather and father.
 * In the anime, it seems Kirara was also the partner of Midoriko.
 * Kirara apparently had very impressive eyesight or senses. In Episode 136, when Sango was invisible, Kirara was able to precisely jump onto Sango's shoulder and put the balls into her hands.
 * Her seiyū also voiced Sugar from Rumiko Takahashi's previous series Urusei Yatsura, Asami from Maison Ikkoku and Wishing Star from Urusei Yatsura (2022).
