Naruto: Wooing Tsunade from Day One! - Chapter 366: The Start of a New School Term

What does “being perfect” mean to you? To Hashidate Yuuto, it means everything. All his life long he strived for perfectness until a single incident occured in middle school that ruined his plans of being perfect: He pooped in front of the whole class and parents. Believing, that his reputation was destroyed and that he would never be able to reach perfectness anymore, he wished that the incident never occured. This is when a mysterious Goddess named Maki offers him a button that allows him to go back in time.

Based on the popular Vocaloid song “” by kemu.

The formless ancient world was infested with despicable demons. They hunted and feasted on mankind, keeping the human civilization constantly in a weak and suppressed state.

During the first known year, a magical mountain descended into the world from the realm of the Gods. Carved on this enormous mountain was a message: ‘Heaven Prevails’…

After the Grand Descent, a name that was given to the descending of the mountain, the Three Great Sages made their ways to Mystic Mountain where they learned to harvest what we now call magic, establishing the Mystic Cults and eighty-one sacred shrines to help aid mankind with the cult’s mystic powers against the eternal fight to the death with demons.
