Shogakukan began streaming a promotional video for the original video anime (OVA) of Kenji Taguchi's comedy manga Ane Log - Moyako Nee-san no Tomaranai Monologue (Sister's Log - Moyako's Monologue That Won't Stop) on Monday:

The manga's story centers on Moyako Konoe and her younger brother Akira. When they were younger, Akira proposed to her, so Moyako thinks he is a pervert who has fallen in love with his older sister. Moyako's misunderstanding leads her to create wild delusions about her brother.

The manga already inspired a drama CD and a fan disc with six Flash anime shorts. Ami Koshimizu (Horizon in the Middle of Nowhere's Tomo, Code Geass' Kallen), Takahiro Mizushima (Kokoro Connect's Taichi, Guilty Crown's Yahiro), and Satomi Akesaka (Wake Up, Girls!'s Reina, Coppelion's Taeko) also starred in both the drama CD and Flash anime.

The manga debuted in Weekly Shonen Sunday in 2012, and Shogakukan shipped both the fourth compiled manga volume and the fan disc on the same day, April 1.
