Kiichi

Kiichi is Setora's favorite nyaa and the last one remaining out of all of those who followed her outside the Hidden Village.

Setora notes that he has a rare combination of qualities and out of all nyaas she has ever seen, he has the highest potential.

Appearance
Kiichi is gray and, just like any nyaa, looks like a mix between a cat and a monkey.

In Parano Kiichi, under the effect of his Narci magic, he gains a radically different appearance. He becomes twice Setora's size, with thick legs and the face of a vicious carnivore. In that form, he is large enough to easily carry Setora and likely big enough for her and Merry at the same time.

He seems to get even bigger later on as he is able to carry both Setora and Enba at the same time, even when that version of Enba is bigger.

He seems to have reverted to his old appearance when he got back in Grimgar.

Personality
According to Setora Kiichi is naturally loyal to his master without the need of harsh discipline.

He has a rare personality that includes tenacity, strong curiosity, adaptability, and exceptional intellect.

He is trust by Setora but also by the other nyaas.

Level. 10 Love Songs Won't Reach
Kiichi, like Setora's other nyaa, help Haruhiro's team while they're fleeing from Forgan by scouting for orcs, Haruhiro noticing that he is the only nyaa the consistently see.

When they notice that they're being target by a guorellas  Setora orders her nyaa to flee but chose to keep Kiichi with her. At first, she was planning to have Kiichi looks for the other nyaa once things, had settled done but it didn't happen.

Now as Setora 's only nyaa, Kiichi continues to act as a scoot under his mistress order, looking for enemies, and providing Setora's food.

Once in Jessieland, he is imprisoned with Setora and Enba. Later like them, he is released when the guorellas attack but didn't do much during the fight.

Abilities
Before Parano, Kiichi was described by Setora as athletic. Being a good spy, Kiichi is able to easily move undetected.

He does a really good job as a scout and in Volume 12, it's said that he did the work of 2 to 3 persons when they were looking for the dragon egg.

Narci Magic:

In Parano, thanks to his magic Narci, each time he kills something it steals part of his prey id and gains more power, as well as becoming bigger and more muscular. In this new form, he is likely incapable of being stealthy but is powerful enough to easily kill most dream monsters and fight with Enba's help against Gomi and Tonbe for a time.

Setora
She is his master and he is very loyal to her, even after becoming way more powerful in Parano. Setora is frequently seen carrying or petting him.

Merry
While all the team like Kiichi, Merry is probably the one who loves him the most after Setora, as she seems to love nyaas in general because of how cute they are. She's frequently looking at him.

Kuzaku
They get along surprisingly well, as Kiichi is seen sleeping on his lap in vol 12, and Kuzaku takes care of letting Kiichi takes his time to wake up when they finally have to move.
