Continuing the naming fun, 'Hako' is 'Box'. Akisora as a name would normally mean 'Autumn Sky', but I'm this case 'aki' and 'sora' can both mean 'empty', so her name would mean 'empty empty box' or 'empty air box', though have to see the kanji for sure. Though even if it uses the 'autumn' kanji for 'aki' it could be a kanji pun.
