If you liked the tv series, first season, then you should watch this OVA. The OVA concentrates more on the relationship with Kurumi, instead of humor and action, and does that in a very clever way... Threw the hole story you are stuck on your screen, because you are suspicious or because you want to know how what is gonna happen... and then it end with a(n) (emotional) bang. The OVA really touched me and even made me cry. WARNING; 1) I discommend to watch the OVA if you don't want people to see you cry and/or if you don't want to cry. 2) I recommend people towatch the OVA alone (and as soon as possible after they watched at least the first season) for the maximum effect.
