I'm really confused about the concept "Metal". They are keep trying to connect it to the "sea" but I just don't see how it connects. Up until now, I actually thought of it as some kind of advance technology network(like internet). The conversation among Haru, Mamoru, and Kushima, sounded too abstract. I just don't understand what happened here. Are they trying to imply that the nature itself(or sea) has tried to connect to the Metal? Haru said something something shook the whole Metal.... and we see that red thing possibly similar to that from episode 1. So my guess is that this is technically the same phenomenon that happened in episode 1("chiku-ritsu"), but this time, inside Metal. So it could mean that Kushima has been able to replicate the sea itself...
About Mamoru, wow. This just brings me back to my economic class. Company like a family. lol. You see how loyal Mamoru is and his fellow co-workers? And the way he cries at the end of the episode ^^;;; This probably is an ideal company looks for Japanese workers who is about 50s~60s. To be honest, I was expecting some darker events this time around, like Mamoru getting unfair treatment and Sota vows for revenge against Kushima... Or we see the dark side of Kushima, or something along those lines. However, it ended up being a heart-warming drama. Seriouly, Kushima is too nice ^^
I guess one big revelation in this episode, was a relationship between Kushima's boss, or secretary general and Sota. I mentioned about this before in episode 3, how the guy slept with the secretary general looks like Sota. I thought it was one possibility and mentioned it, but was skeptical that that is the case. What do you know? 0_0;;; It actually WAS Sota! That explains where the secretary general in that episode got the info about Haru from ^^ This kinda complicates things between Kushima and Sota (Sleeping with your boss complicates things even in real life ;p This will definitely complicate things in anime) I wonder if they are actually in love, or one of them is using the other (or both of them using each other;;; At least secretary general seems like she is satisfied with sex ;p) Her smile is so suspicious... Anyhow, secretary general is about the only one who is doing some proper service scene in this series. (Now that I think about it... it seems like she is about the same age as Kushima... ~_~ and it seems like Sota is in his 20s... uh....)
*p.s1: I think this is the series I'm enjoying the most this season. ~_~ kinda sad how this is the least popular series on my blog.
*p.s2: System down this episode reminded me a lot of Magi system down from Evangelion...
