Talk:Nana Ebina/@comment-94.197.121.116-20160114230907

Can anyone answer for me why the other characters address her as Ebina (her family name) when everyone else seems to be on a first-name/nickname basis and she uses their first names (or nicknames or "Onii-san")?

The only reason I can think of is that is how she introduced herself to Taihai and perhaps how she got introduced to Umaru... Unless ther's something I missed in the anime or a cultural element I have no knowledge of?

Thanks in advance
