Makimura Koutarou has made up his mind: during the summer vacation, he is going to confess his love to the seemingly unapproachable Serizawa Kaho. Yet, on the night before, he has a run-in with a strange girl - an encounter which propels him into the future. There, he learns that not only has Kaho-chan become his girlfriend, but she has also died in a tragic accident. Returning to his own time, Koutarou sets out to change the future and save his love.

This is basically Steins;Gate before S;G was a thing. It's not bad, but it really isn't too excellent. With only 2 episodes, it definitely leaves much to be desired. I understand that there really isn't much they could've done with so little space, but it's still just disappointing.

I haven't played the game, but judging from the story here, I'll assume it's at least decent. The art, sound, blah blah blah, are all pretty ok with nothing too special. The characters do act rather stupidly.

Overall, this could've been a decent series, had they made it into one, but that's not the case..

So I was bored in a free period at school today and I decided to randomly go through MAL pages until I hit something vaguely interesting. I happened across a page on the producer of this and saw this...it sorta piqued my interest, so I watched it.

I am so happy I was bored enough to find this gem.

Natsuiro no Sunadokei, in my opinion, is what a romance anime should be. I really hate romance anime where the guy is a perverted idiot and the girls are stereotypes who throw their fanservice-prone-selves on him either willingly or unwillingly. Thankfully, Kou has a brain read more

Yeah~ I gave this a 10 ^^ I haven't played the game so I don't know if this OVA does it justice or not, but I enjoyed it anyway.

I've never seen anything quite like it. I will not go into what the story is about because it's in the summary up at the top, but it's very different from all those other 2-3 episode long OVAs out there. It is beautiful and different and is very well presented, even though there was only 2 episodes to work with. If it were to become a proper TV series then I'm sure it would be popular :3

Well, I have in fact played through the visual novel.. So I can say I enjoyed both though I gave the Novel a 10/10

The OVA Follows as best it can the Kaho Path - It changes a few things here a few things there, and it does change the ending a bit to.

But if you take the OVA for what it is .. 2 episodes - it is well done for that. The characters are surprisingly well done for 2 episodes - as is the general plot explained surprisingly well for such a short ova. (When it was a far longer Visual novel) read more

Anime: Suzumiya Haruhi no Yuuutsu (2009)
The Endless Eight really reminded me of this OVA involving the theory of time travel/loops. There's also some emotion and drama in both series as well as comedy. (more in Haruhi). Both anime(s) are something to keep an eye on.

Anime: Ushinawareta Mirai wo Motomete
It seems like both of these animes have time travel in them and also, someone they love dies/gets hurt and both MC want to bring them back to how they were before.

Anime: _Summer
Both have the same feeling and are eroge adaptations. Both are 2 ep. OVA.

Anime: School Days
The same plot where a boy is surrounded by many girls. The same type of love triangle. The main characters share the same personality: the boy is in love with a shy beautiful girl and asks for help to his friend which is a energetic girl that is in love with him. But, They differ a lot in the end, one has a happy end, other has a tragic end.
