Sawamura Eijun wakes up and realizes he's shrunk: "...Huh? Why am I little? I've never seen this happen before."
Why is my house in Tokyo? Sentinels? Guides? What are those?
What, I'm a Guide? Whatever! Seido, here I come!! This time, for sure... I absolutely will win!
P.S.:
1. New story, a rebirth story. Eijun is reborn in his third year of high school and discovers that the world has changed.
2. The story centers on Sawamura, with Sentinel-Guide dynamics.
3. There's only a little baseball. The focus is on sweet everyday moments and a love-triangle-like situation that the oblivious protagonist doesn't notice.
