(And now to fill in the space I shall write random stuff in Japanese):

初めまして、私はライアンです。１５歳です。二年前くらい私は日本語を勉強する。今年の十二月で私は日本語能力試験をする。私は犬がいる。可愛いですよ。彼（私の犬）のニックネームは「子犬」ですよ。えと…私の友達もここにある。私の友達はすごい。音楽が上手ですよ。コーナはギッタがすごい上手。私は赤毛ですけど、私は「毛の色が大切じゃない」って思う。でも、時々、毛の色に冗談する

(And now cause I feel like it I'll translate that into English, even if I've said it before)

"Hello, my name is Ryan. I'm 15. About two years ago I began studying Japanese. This year I'm going to take the JLPT(Japanese Language Proficiency Test).
I have a dog. He's cute, therefore his nickname is "puppy". Um.. Some of my friends are also on this site. My friends are awesome. Both are really good at music. Conor is awesome on guitar."(I was running out of things to say)," I'm ginger, but I don't believe that hair colour is important.Although I'll joke about it sometimes."
