Informative review. Again, had somehow missed out on this, idk if MAL was being drunk or if I am more blind than a mole. Either way, I have come to this. So what does TWGOK Natsuiro Surprise bring. A music video. That is pretty much it. A 2 min music video dedicated for the Kanon fans, (the entire song is actually 4 mins, however) It plays out first with her in a swimsuit rolling around and whatnot, but as it closes to the end it plays as if she were at a concert with special effects to accompany her for the sake of making things more livelyI guess. The song is quite alright, but I am sure as hell that if this is not on repeat 24/7 you will probably forget this. And maybe the music video itself if you happen to have a bad memory.
Worth the while? If you are a completionist, go for it. Even if you are not and want extra TWGOK, 2 mins won't hurt. Though you may be slightly disappointed.
