@HOOfan1 If you have no problems with the sound, that's fine. A lot of people just need practice, or to hear the proper pronunciation to do it. Definitely make sure you're getting the t sound on tsubaki though.
As an aside, tsubaki is the name of a tree which is well known for producing a flower with no smell. In literary works, this name is often used as a sort of symbolism for women that have an inherent beauty which isn't immediately obvious. I've personally always thought this was kind of uncalled for because it overlooks the fact that an extract made from the leaves is a VERY strong poison. In the case of Tsubaki from Soul Eater, it was kind of a nice descriptor, but that's a rare instance because it usually gets used for the wallflower type characters.
