Unlike a lot of people that have seen these OVAs, I've actually
seen the TV series that Knights of Ramune is based on (and a bad one at
that). Knights of Ramune is a mix of hyper cute character designs, decent
mechanical designs, and a ton of fanservice. It's a pretty strange mixture of
visual styles. The plot stacks on top of the TV series, with the girls looking
for the most recent incarnation of the warrior Ramunes. The fanservice however
is a tad more overboard than the TV series. We're talking magical powers that
require characters to get naked and masturbate, plus a mech that can only be piloted
naked. The comedy is light, with lots of sex gags, and the show seems to throw
out random fanservice whenever things slow down. People who've seen the TV series
or that are looking for lots of fanservice may want to watch it just to see it,
but most will want to avoid this one.
