Um, Happiness! OVA started off with its usual roundabout storytelling method, but picked up pace after Jun turned into a girl. Not especially surprising storyline.
[Mood: Light]

Very straightforward story, albeit strange. Strange as in some characters had personalities a bit off, a new character hugs Saya, Ibuki attacks her best friend and etc.

I like the part where happiness was spread, as a tribute to the show's title, which the original series doesn't really seem to show.

The colours were a bit dull, but it's still ok.

Nothing special here...just Jun transforming into a girl after a combined magic hit's him.


Kindda dull...I was expecting more of this OVA so it's my mistake here.

If you like Happiness! as a brainless, fluffy slice of life show and don't want to think about it too much, you might enjoy this.

If you dislike Jun as a character, you will hate this.

I enjoyed Happiness! a bit more than most people but it was a while before I watched this. I was always kind of interested in it as Jun was my favourite character so an episode focused around him sounded appealing. He's cute and unabashed and open about his dress habits and he's queer as hell. He's a great character there ...
