Story:
The story has a nice flow. Like all mecha series, it got fantastic mechas with specialized specification for each mechas, skills training and conflict between characters, powerful enemies and realiable reason(s) for fighting. Not to mention 'best friend theme' where we can find alot in other anime is also included.The start of this anime which shows peaceful school days for main characters, Kazuki and his friend make a nice twist when the secret of the island and the reason the island is the last line of defense is exposed. As we goes more into the episodes, more secret/mystery will be reveal. I guess that was attracted me the most. The anticipation of 'what's more' and hard to guess 'what next'.
Art and Sound:
I have no comment on the arts and sound due to my limited knowledge. But I would say, the arts and sound is good, really helping in making you enjoying the stories.
Character:
All the characters are well made. The relations between the characters are well explained and there's nice development of characters along the series. What interested me the most is, how fair development of characters is given to all cast, not only focusing on the main characters. You will also noticed the variation of attitudes and issues between the casts is brought up in the series.
Overall , I enjoy the series. It's one of the series where I can't put down until I finished it. And I would love to have a rewatch of this anime *if only my sis will return it to me rite nw*. The only reason the anime didn't get a full 10 from me is due to ending which left me a little unsatisfied/sad. But it's the matter of opinion. But really, it's only the last part that I'll leave it to your opinon, the rest of the anime is great!!.
