Japanese to English

"White demon".

はくちゃんは　いい　ですか。

Is Haku all right?

'Shi o imu' would mean 'to avoid death', without the o in between it is a name, meaning literally 'ocean view'.

"Hontou ni doumo (arigatou gozaimasu)" means "truly thank you very much!"

Omoshirokatta, or 面白かった means:

It was funny/interesting

wife

Though name meaning depend mostly on the characters used to spell them. From what I gather, Ginza means "Silver Coin" or "Silver Coin Mint"

In relation to land, "chiheisen" (written 地平線); in relation to a body of water, "suiheisen" (written 水平線).

'Oyasumi' is said to someone before sleeping, generally translated as "good night." 'Aitai' means "Want to meet."

派手 (hade)

It means I love you.

I believe the Japanese word is キャスト (kya-su-to) which is Cast is English. If this does not work with your text from which you got the romaji or the sentence does not make sense then perhaps you misspelled the romaji. Remember that lines over vowels makes longer vowels, which can change a words meaning entirely.

I am your true happiness.

It should be 'Kiotsukete kudasai'

Kiotsukete - Be Careful

Kudasai - Please

So, it would mean 'Please be careful'

Just on a side note, if you just say 'Kudasai' it means 'give me' in a formal way

It means 'firefly.'

Assassin in Japanese is 暗殺者 (ansatsusha).

You misspelled that, but from what I'm interpreting, it means "What is your favorite animal?"

Wild Orange.

i wish a woman would say this to me

it means

"please use me"

otsukaresama = Thank you.

Tsukasa (つかさ) is often used as a girl's name in Japan, and sometimes it's used as a boy's name too. We also have several towns/villages named Tsukasa. The meaning might differ depending on what kanji is used.

It's pronounced Keeb-ah.

land of riseing sun
