Kemeko, the mobile suit, is really annoying and too ugly for me to handle (intentionally so).

It's like a really absurd spin on the suddlenly-girlfriend subset of ecchi. The series is weird to a fault. There seems to be a similar sort of Medical Mechanica (from FLCL) conspiracy going on as well. I guess you could say this is a Mecha/Excel Saga/FLCL suddenly-girlfriend type of series.
