Oh I'm not really about to defend this steaming pile of fertilizer, it's an ecchi harem show and that in itself is enough reason to assume it has terrible story and can only gain points from things like comedy.
Okay boys and girls, lets take it from the top!
Story: Bunch of idiots with a train / action / main character fetish, in pursuit of their dreams they summon a magical portal to the realm of plot convenience that forces the most mathematically astoundingly unlikely and logically impossible events the human mind is capable of pulling out from between the lower back cheeks. Expect around 16-18 times more boob flashes than displays of common sense.
Art: If you only watch stuff like this for pretty scenes and curvy women this is a highlight no doubt, many scenes are quite a sight full of bouncy delight.
Sound: Aside from the pathetically hollow main guy the cast has pretty decent voices and the soundscape is actually rather good.
Characters: Pretty sure this is what it would look like if you'd kidnap random folks from mental institutes around the world, so bad it's actually a bit entertaining.
So how does this add up to a full 6, and a reviewer almost wanting to go for a 7 at that? Well the above doesn't but there are rather numerous moments of entertaining stupidity and if you don't take a single moment seriously it is in fact a pretty funny show. Also boobs.
