It has been a long time where i could not stop watching an anime show continuously episode after episode without rest. This is a mostly dialogue-driven show about college students discovering time travel and the common consequences of said time travel. Extremely memorable characters and top notch pacing that is really missing in other anime shows. The science behind the time travel is nothing complex, but the writers used the time travel in an incredibly brilliant way to flesh out all the characters to the fullest possible extent. Very funny show as well, since the main character is a neurotic who can't view his work objectively and somehow manages to get all his partners to stay with him. This may not be a flawless anime, but it certainly one of the best, I promise you that.
