As its TV predecessor, this Fat Elf ONA treats the viewer with thick and chubby hot waifus in sexy situations. I have to say that it's more fanservice centered here, for example the first episode (13) has all of our favorite girls in bikini at the beach, imagine all cliches you already watched in anime and you'll see it here in 12 minutes, I had fun seeing everyone having a good time, no one escaped the ecchi factor, not even main guy. Second episode (14) is a pure high school romcom with main guy being a shota now and surrounded by hot thick colleagues who want todo ecchi things with him. Setting being changed means that no one tries to lose weight so we lack the usual comedy skits but the good thing is that we get comedy from different angles which is totally fun, made me laugh even though I watched hundreds of school ecchi comedies, the girls made it worthwhile.

Art and animation are consistent with the main show, they even play the OP and ED, sadly no big improvements, movement in this ONA looks as lanky and limited as it was for the TV.

A definite watch if you liked the TV show
Be sure to watch if you enjoy ecchi with thick girls
