Who voices Eru Aharen in Aharen-san wa Hakarenai?

Just like we were introduced to Aharen-san’s little brother Ren in episode 6 of Aharan-san wa Hakarenai, this week Aharen’s younger sister Eru Aharen showed up in Episode 9 of the popular comedy anime.


A sister Raido meets when she is outside a sword shop choosing ‘a big knife’ for cooking.

And a sister that is more than just a little tsundere. Especially when it comes to protecting her beloved Reina, who she loves more than anyone.

But who voices Eru Aharen in Aharen-san wa Hakarenai, and how many anime roles has she had in the past?
