This makes it a lot easier, as all Ova episodes can practically be accommodated in one rating.
The first 2 Ova episodes are mostly humor-oriented and have no relevance to the main story. Among other things, they have a significantly higher fan service share. Especially as you would expect from a "Beach Episode" and "Sumo".
Nonetheless, they were at least humorous and the fan service was ironically very balanced. It was actually amusing how both the men and the women got into exactly the same situations.
The other 3 Ova episodes do not have great relevance to the main story either, but their events are addressed minimally in the first episode of the second season.
For the most part, they were average and corresponded to the level of a normal everyday episode in this story.
You can watch the Ovas, but if you are not interested in the characters' screen time but in the story, you should skip them.
