What's wrong with it? I'm comparing to striker2 which had a few updates to the legends and it looks the same
The
を legend is too small. It's supposed to be the same size as the
わ below it (unlike ぁ, ぃ, ぅ, ぇ, ぉ etc., there is no small を kana).
It's pretty minor all things considered, and I'm not faulting the set for it — it's just annoying that we've been trying to get hiragana legends sorted out for years now, and it still hasn't fully worked out. I hope we have less of these problems in the future once Serika 2's new hiragana molds hit the tooling machine.
