"'Newton' was actually the pen name of a brilliant-minded girl!?" Protagonist Asanaga Shuuji and his childhood friend Utakane Yotsuko, whilst tracking down Shuuji's missing grandfather, unexpectedly ended up travelling through time. What they witnessed upon their arrival was the presence of a single girl right in front of them. This particular girl would go on to be dubbed as the father of modern-day science, Sir Isaac Newton! That's correct, Newton turned out to be a small, flat-chested girl! Unaware of this, Shuuji loudly crashed into the apple tree right in front of the girl. "Just now... I came up with something that might be incredibly ground-breaking, you know!?" It was at the moment our main couple travelled through time, right then and there, that Newton discovered universal gravitation! And just like that, through Shuuji's witless conduct, the great scientific discoveries of that century had all crumbled to ashes. What's more, like the domino effect, this would gradually end up altering key points in history. It is now sometime during the 17th century! The story is set at a prestigious English university called "Tenbridge University", named for the fact that it spans a total of ten bridges! Will Shuuji ever be able to rectify history and return to the present!?
