Nekomata (猫又, lit. "Forked Cat") are one of the species of Youkai featured in High School DxD.
Nekomata are a cat-like species of Youkai which specialize in using ki within the East Youkai Faction who are under the rule of Magari, the leader of the Nekomatas. The Nekomata mainly consist of female, with male Nekomata being rare among their species.
Female Nekomata generally mate with the males of different races, mainly with human males, due to the traditional teachings. Female Nekomata have a "mating season" where they go into heat, as seen by Koneko Toujou, who went into heat and attempted to seduce Issei in order to have his baby. The childbearing age range appears to differ compared to human women as seen with Koneko when Kuroka stopped her from mating with Issei, explaining she was too young to risk pregnancy although she was 16 at the time.
Nekomata bear a striking physical resemblance to humans, albeit with a set of cat ears and generally have two tails. They also have eyes with cat-like pupils. The only exception to that is Magari, whose appearance is completely that of a cat albeit with seven tails.
Being a cat-like species, Nekomata naturally have great reflexes and heightened senses.
Nekomata's are capable of transformation to appear more human, however this supposedly limits their natural capabilities to a certain degree until they regrowing back their ears and tails, it's not specified if they can fully transform into cats.
Nekomata are also capable of performing Senjutsu and Youjutsu techniques. A Nekomata's power level seem to be determined by number of tails they have, as exampled by when Koneko grew a third tail and surpassed her sister in terms of strength, this also would explain how Magiri has seven tails.
Matured Nekomata's have control over their mating season, as was shown by Kuroka, who didn't let her desire for mating cloud her mind, but young Nekomata like Koneko do not. They also appear to have this control overs since Kuroka was able switch off her sisters heat and when Magari was able to switch it back on for her and Kuroka from a short distance at any time.
The Nekoshou (猫魈 Nekoshō) are a special variant of Nekomata and are the strongest among their types. Nekoshou are high-level Youkai species that are capable of mastering both Youjutsu and Senjutsu. Currently, the only known Nekoshou are Kuroka and Koneko Toujou, both of whom are said to be the remaining survivors of the species.
- In Japanese mythology, Nekomata Youkai are stated to have a tail that is partially split in two, like Kuroka, but Koneko has been shown to have only one tail, mostly due to the fact that she is still young and has yet to fully mature. Later in the series, however, she was shown to have two tails.
- Currently all known Nekomata have been reincarnated into Devils with the exception of Magari.
