This... is simply brilliant. The author clearly knows what they're doing and the characterisations, descriptions and dialogue is all spot on. As for the actual plot... Mamoru is no
Marty Stu. Whilst he wins, it's always through sheer luck and bloodymindedness
until they start finding the other Senshi and he always,
always gets the crap thoroughly beaten out of him in the process... between nearly dying every time he has to fight,
one girl in particular not responding well at all to the discovery of her senshi-hood, the team getting targetted by
Beryl's Dark Generals, who eventually get desperate enough to actually start killing people, the story maintains a brilliant tone of desperation and determination, that pulls you along throughout the entire story... It's just brilliant, really. Blasts all the others out the water and into trees; go read, now.
