The story is fine. However too much effort is wasted on ecchi and some slow motion you-know-what part. 4/10
Shinichirou is like a support character, simply there to resupply the energy of the girls.
Nothing to complement/complain about the sound or music.
The art is done quite nicely but I can only give a maximum of 4/10 for it because the whole battle scene is basically censored thanks to all those ecchi and seinen contents.
The action + seinen combination in this anime is one of the worst I've seen. Also, whats with that ending?! It felt like 2 episodes or more being cut off directly. Overall 4/10 with tons of question marks in my mind what the heck I just watched.
