Cosplay (コスプレ, kosupure), short for "costume roleplay", is a type of performance art in which participants don costumes and accessories to represent a specific character or idea. Characters are often and fantasy drawn from popular fiction in Japan. Favorite sources include manga, anime, tokusatsu, comic books, graphic novels, video games, hentaimovies..
And here we mention Akuma...
For her it's just a hobbie that alouds her to develop lots of skills (fashion, performance, styling, etc) and, as she says, also is fun.
That's why she doesn't dress that way daily, although this hobbie for someone that doesn't know her might be confusing:
"... What you can usually get to see is when you tell someone 'i do cosplay and you explain what's about, they stare as if you where crazy! and they say, why don't you get a job, mature, or make more interesting things? But they don't realize it's just a hobby...There will always be prejudices around things people doesn't understand or like... i can't fix every thing they missunderstand, so what i would say is get informed and respect, nothing more...
When people so committed to the style are faced, such as Akuma, some inevitable comparisons arise....
¿Does being androgynous is potential to homosexuality?
Firts of all, the Androgyny is the quality of the persons whose external features are not specific or male or female. Clearly not directly related to sexual orientation!
¿It is mandatory that being an Otaku includes being a Cosplayer and Visual?
First of all, Visual kei (ヴィジュアル系 bijuaru kei refers to a movement among Japanese musicians, , literally "visual style") that is characterized by the use of make-up, elaborate hair styles and flamboyant costumes, often, but not always, coupled with androgynous aesthetics.
While Otaku (おたく / オタク) (oh-tah-kooh) is a Japanese term used to refer to people with obsessive interests, particularly anime, manga, or video games. In Japan using this word may be ofensive to some people.
So, it is true that all these styles came from Japan and have some similarities... anyway that doesn't mean you should belong to the three of them (but you can if you like).
Finally states that, while this like all social spheres, is full of competitive and dishonest people, the main recommendation for all would be...
"...Be happy and do what you like, cause the world is full of people that will dislike what you do and will try to change you, but if you are going to listen to every stupid that judges we wold definitely go crazy.
If you are doing some kind of hobby, that you enjoy a lot and doesn't hurt anyone, feel free to expres yourselves. Have fun!..."
