Nanoha using 'befriending' as an umbrella term to describe her lesbian activities would actually make much more sense in a conservative medieval setting.
We started with Bardiche, went to Cardiche and now arrive at Horcediche... sorrynotsorry.
Anyway, more NanoFate is always welcome, specially at the start of the year.
