Ok, what we have here is generally is a 1 off OVA of the parent anime "Toradora," it still follows the same genre and it still maintains the same cast, however this is one OVA that should have been included as an episode of its parent anime instead of a separate OVA. So my rating:
Story: Good 7.
Ok, so the OVA is all about Ryuuji who is having some insecurities of losing out to Yuusaku's grandmother who happens to make a good bento meal for the latter, so he does all the unnecessary things that he can to beat his best friend's grandmom's cooking, which overall it is the comic part of this OVA that makes it to have such rating.
Art and sound: Mediocre 5.
No need for me to say on this parts.
Character: Mediocre 5.
I did mention that the original cast of this OVA are still here.
Enjoyment and Overall: Good 7.
I not gonna elaborate anymore, all I can say is that this OVA is worth watching and one has to think of it as a long awaited episode that is finally been aired.
