The way I learnt the japanese alphabet was actually by making a phone keyboard layout and printing it off, I didn't know it was alphabetical order but yeah it makes sense
The order starts from centre, then goes left, and clockwise around, and then to the next group to the right (and down) e.g. a-i-u-e-o ka-ki-kuk-ke-ko sa-shi-su-se-so ta-tchi-tsu-te-to etc.
They are both really cute, but Ayaka is doing everything or more like she is getting all the development, Sora is still the same, hiding and waiting. Maybe Mom will be the push that Sora needs to actually stop avoiding all her problems
