Hello!!
I want to talk about Otaku, and related words.
Firstly, I think Otaku means someone who have extremly specific knowledg about some area. For example, Tetsudou Otaku means someone who knows the subway, trains,and so on well. Although we respect those people because of their special knowlege, some people disrespect them. Unfortunatelly, Otaku is not recognized preferable people.
Second, Moe is one of the feelings. When we see a cute or pretty thing, animal, or action by human, we feel our heart pounding fast, which is Moe feeling.
Thirdly, Tsundere is one of the attitude. Although Tsundere people act sadly and chilly toward a boy in front of the people, once there are only she and he, she becomes to fawn on him, which is Tsundere People's character.
Finally, I would like to talk about Burikko. It means the women who pretends to be pretty and cute. They often pretend to be weak and cute girl to get attention from others.
Otaku culture has been developing now!!!!
