Here you can read a short interview with a Japanese cosplayer on the learning site Hirogaru Nihongo. She remains unnamed unfortunately.
All her answers are transcribed into simple Japanese and you can watch a video of the interview with her original answers afterwards. In the end, there is also a little reading comprehension quiz.
The [RUBY: OFF|ON] button in the top right-hand corner can be used to switch on furigana, but unfortunately this function cut off the text for me.
It didn’t bother me much, however, because you can simply have each paragraph read out to you with a simple click.
You can find the interview here: https://hirogaru-nihongo.jp/anime/article/cosplay2/
Length: ca. 300字
Since the text is relatively short, I can recommend also reading the article named 「コスプレ写真」, where the same cosplayer explains how she takes her pictures.
