I wonder why the other two members haven't articles here. But from OVA's page in the Japanese Wikipedia. I found their name and their voice actors:

  1. The man is called Iwana (イワナ, Iwana) and his voice actor is Anri Katsu.
  2. The woman is called Yamame (ヤマメ, Yamame) and her voice actress is Rie Saitō.

That's all. —Shakhmoot Nadeshiko Village Symbol (Talk) 08:44, December 23, 2012 (UTC)

Done, but they need some expansions for the appearance and personality. —Shakhmoot Nadeshiko Village Symbol (Talk) 14:18, December 23, 2012 (UTC)
