Can anyone help me find the Japanese word and symbols for ''victim''?

Need to help someone with something, and looking it up online, I’m not finding much. At least, most of those sites seem to assume that I already have a basis in Japanese, which I don’t. Plus there are three alphabets, so this makes it all the more confusing.
Anyone know the word for victim in Japanese, and the associated symbols/letters? The word needs to go on a costume. ’‘victim N.777’’.
Thanks. :)
