Kyou kara Maou

Story:

Yuuri Shibuya is an average high school student whose passion in life is baseball. That is, until he intervenes in the bullying of a classmate, Ken Murata, and gets his head dunked in a toilet, which sucks him into another world. When he reaches dry land, he sees some people dressed in medieval costume. He assumes that it is a theme park. However, the people are afraid to see him and begin to pelt him with stones. Conrad Weller and Günter von Kleist rescue Yuuri and take him to Blood Pledge Castle, the residence of the Maou, who he soon learns to be himself. He meets some key characters, his fiance Wolfram for one, and soon finds himself being called the 'Maou', or Demon King. There, Yuuri learns he is to be crowned king and rules over 'Shin Makoku'.
Throughout the series, Yuuri is constantly confronted with the results of even the smallest choices he makes. With a strange power dwelling inside of him, Yuuri becomes a deliverer of justice in the world of Shin Makoku.

Lyrics:

Hateshinaku tooi sora ni(opening theme song)

Hateshinaku tooi sora ni "Arigatou" no kimochi dake
Todoku you ni ryoute hirogete warau

Chiisakute kowaresou na inochi no kakera o kimi mo boku mo
Hitotsu-zutsu motte iru

Shinjitsu no hikari wa Akarusa o mashite iku
Yami wa kiesari Kimi no kokoro ga mirai o terasu

Hitotsu yakusoku shiyou Boku wa koko de ikiteru
Aru ga mama de ii Mitsumeyou masshiro na iro

Omoi wa yagate itsuka Unmei ni tadoritsuki
Kagirinai tsuyosa Mitsukeru n da

Shinjitsu o motomeru n da Kanashimi ni uchihishigareta to shite mo
Makesou na yoru de mo

Shoudou wa shizuka na Toki no naka de umarete
Kakugo o kimeta Kimi no kokoro wa Subete o kaeru

Hitotsu yakusoku shiyou Boku wa koko de ikiteru
Aru ga mama de ii Mitsumeyou masshiro na iro

Omoi wa yagate itsuka Unmei ni tadoritsuki
Kagirinai tsuyosa Mitsukeru n da

Hateshinaku tooi sora ni
