Danchigai: Juusan Goutou Sentou Ikitai!! (2015) First off, I see a few low scores on the basis of it being a bathhouse special. Let us be clear unless you have that attitude to every single show that does this then the opinion is invalid as it will depend on the order of shows it became boring for you. If this was your first it would be amazing surely in comparison to ones you haven't seen. The OVA is literally episode 13 which comes to why I wished the episodes were longer or had more episodes in the season so that this could have been with themain series.

As you would expect male and females are separate. The 4 girls do some lewd things very mildly and the male has a fantasy.

Ends with Yayoi and the brother Haruki having a comedic gaff as with their normal scenario that doesn't go as planned for him and leaves on a funny yet light note with the other sister's reaction.

The art is the exact same standard as before.

The sound is good too, the ED is fun still.

Characters are generic as they are the same:

Brother = Simp.
Older sister = Cool in public, lazy at home.
Middle sister = Brocon but tsundere.
Twins = non-identical, one shy and one active but love pranks.

In the end, another fun episode that leaves the show on a high.

Shame it didn't continue.

7/10
