The anime blends history with comedy, drama, and a little parody, which is also one of the reasons why this is unique. A boy seeing the dark history of this place through time travelling with the phantom of an unchanged 60-year-old, meeting older people and changing history little by little.
The opening theme is "Oyasumi Paradox" by Etsuko Yakushimaru and the closing theme is "Otome no Junjo" by Ryoko Shiraishi, Kaori Nazuka, Ai Nonaka and Yui Horie.
