Tennis no Oujisama: Another Story - Kako to Mirai no Message

The first 2 episodes were very funny, I was dying at some points. Certainly take your time to watch these side Prince of Tennis shows because they provide a lot of background history on some important characters and show how they came about. It's just as the title says "Past and Future".
P.S. The OVA Bonus that has the same title as this one but with OVA Bonus on the end and only has 2 episodes is actually identical in material to this title's episodes. The OVA Bonus is actually the first 2 episodes of this title. Regardless, enjoy the content, it's great.

The Osaka set OVAs are good for overall character development despite the super rookie who can’t pronounce Echizen’s name correctly needing a good smack. The other two OVAs focusing on the backstories of Atobe and Kirihara just make you wonder what kind of parents let their children grow to become prideful narcissists. Only the Osaka OVAs are better than the previous content. This franchise seems like it’s never going to move past its crucial character problem as it sorely needs to change its characters in order to move on and actually be interesting. Now onwards to TeniPuri 2! I have to hold out hope that ... the franchise will improve on its fatal flaw of prioritizing Shonen visuals over comprehensible stories.
