You see my ninja HA on the left of this very post. (Or at least I hope so. xD) My theme is targeted to having a ninja theme with an ice/snow twist.

Just to be clear, I don't have the entire ninja costume box collection (I only bought the half ninja mask).

I'm also planning to get Icekiss and possibly Kyokou, if I can raise enough money. I just want some kind of ninja/ice weapon.

Any suggestions?

I think it's good that you haven't used the entire ninja set, as it makes your HA much more original. It looks good so far. ^_^
