*Eating a whole buffet of food by herself*

Mmph... Pheasd to pmheat youf... *gulps it down* My name is Yako Katsuragi...

I've just gotten back from saving my mother from jail~ Gosh, my profile looks so bland~ I wonder where Neuro's been? I hope he hasn't let any of his toys out to terrorize the city...;;

Anyways, let's become friends! If there's a mystery you need solved, come to Neuro- I mean me! T-The Katsuragi Yako Demon Detective agency is at your service~ hahahaha

[[Yako is a young girl with short blonde hair (which becomes long when she merges with Akane). She wears a pair of red hairclips, one on each side. The hairclips are shaped like a grinning mouth with sharp teeth. Yako's usual attire throughout the series is her school uniform which consists of a yellow sweater and a green skirt in most of the coloured manga depictions or a pink sweater and grey skirt in the anime's depictions. Yako has an insatiable appetite -with a cast iron stomach to match-, and a knack for understanding human psychology that occasionally provides Neuro with information he is unable to obtain, due to his unfamiliarity with how humans operate. Yako is even able to understand Neuro, to a degree.

Neuro enjoys abusing her and, as she has stated many times before, has forced her to go through a lot of humiliation and torture; but despite their sadomasochistic relationship, Yako displays true affection and concern for Neuro, considering him to be one of the most important people close to her. Although Yako does not possess any actual skills for combat, she can stay relatively calm during high-stress situations, though she may ocassionally be shaken up when she encounters supernatural foes like X.

She also has high observation skills as shown when she easily deduced the kind of lifestyle Fumio Honjou lived just by looking at his belongings. While these abilities do not seem very significant at first glance, they have proved to be very vital in the series as Neuro lacks the ability to understand emotions and feelings, putting him in a disadvantage in certain situations as seen during the HAL arc when HAL easily countered Neuro with a password block. She is well-liked by many people, is able to form and maitain social bonds easily, and shown through the series to remain somewhat close to many characters.

Besides that, Yako's other ability would be her love for food and culinaries. She has an incredible appetite and is able to consume almost any kind of food, and in superhuman quantities. This is said to be the result of her mother's incredibly horrible cooking skills which has trained her to be able to take in anything. Haruka's cooking has also caused Yako to develop her own culinary skills which, while ocassionally dabbling with odd ingredients such as common weeds, are far superior compared to her mother's.]]
