It's my first post here and I hope someone can help me out.
I am writing a story set in Japan with two female twin . Their parent are both from old and prestigious family, related with the Emperor. One of the family is old fashion while the other is more modern. The girls are cute and loved by their parent.
I need help to find the twin a believable Japanese name. The trick part is that I want them to incorporate a pun think by their father who is an assassin and like to be sarcastic.
For clarify, one of the girls name I think of is "Shirayuki" because it can be abbreviate in "Shi-chan" which can mean "Little Death".
Now I need help for the other twin. I will appreciated it if you suggest the kanji in which write the name as well.
