Both shows are slice-of-life anime that seem fairly mundane at first (even if you consider Ikamusume a fantastic creature), but are very surreal underneath. Both series also feature loveable characters that seem natural and unique.
Both Samurai XXX and Spaceship Agga Ruter have a young man in the leads who is naive and charming, but at the same time very proficient in bed. There is a unique, strange innocence in these two characters, which places both animes in a cheerful, upbeat light.
Kanamemo is also a comedy with all-girl cast. The humour might be a bit different, but while watching Kanamemo I couldn't help but think about Azumanga Daioh characters! Hinata is a lot like Kagura, Kana's imagination immediately brings Osaka to one's mind, and Yuuki & Yume are a lot like Sakaki & Kaorin might be if they ever got together. Even superdeformed scenes in Kanamemo are closely mimicking Azumanga in style.
