* FanDisservice: Fans of the original anime were hoping Ayunosuke was Koinosuke reincarnated. They were deeply disappointed when [[spoiler: she turned out to be his daughter.]] Koinosuke/Juubei shippers were also upset that [[spoiler: Koinosuke must have had a secret wife]] for this to happen at all. Lastly, some fans of the first season were not at all happy with the 2ed seasons heavy LesYay fanservice that was not present in the previous season.
* TheyChangedItNowItSucks: Season 2 had a very different tone from season 1, many characters did not return, & it lacked the humor & genre satire.
* ViewerGenderConfusion: Ayunosuke. She looks 5; her clothing consists of a bunch of rags that look like a boy's. It's not until the final episode in the second season that her clothing "reverts" in age to very distinctly female clothing. Given a LampshadeHanging right after that scene.
