Tetsuwan Birdy Decode - The Cipher is the intermission between the first and second seasons. This was released after the 2nd season aired.

This 25 min OVA introduces us to some of the players central to the story of the 2nd season, gives us more of the characters we love, and rehashes an old short joke from the 1st season. I can't really go into details without spoiling anything, but it has a little bit of action, some sweet moments, and the occasional bit of comedy.

The entire series just has this special charm about it, and this OVA is no exception. So if you enjoy read more

I watched this OVA before I saw season 2 of Birdy: Decode so I was helped out as I entered into the second season. At the time I watched it though I didn't know how helpful it was actually going to be when making the transition.

The story seemed to lack any real punch, like it knew it was just supposed to bridge the first and second season and didn't have much real substance, which is fine for an OVA. A few season 2 plot points got set into motion which was nice and it did somewhat answer my question of how relevant Nakasugi read more

Well I just finished watching it about ten minutes ago so here are some words about it.

Well ill start by saying its easier to under stand if you have watched the first session as it is set between the first and second, but there lies one problem as it was aired after the bloody second session.
Cant they of aired it before so we knew why that person was like that and the other was like that and where the new guy came from?
(no spoilers there folks).

Well it is a Birdy series so its got the usual sci-fi stuff (like a bizarre Terminator thing that looks read more

Tetsuwan Birdy Decode: The Cipher

To be honest, I'm a little surprised. In the sense that the ova is actually irrelevant. Yes, it is the transition between seasons 1 and 2 and shows the aftermath and current situation of the protagonist's girlfriend from season 1.

"Possibly" this would have played a role later, but since this is irrelevant to season 2 and probably would have only been picked up again in season 3, there is no need to watch it.

It's just an everyday life episode, even if the average quality of this ova episode, exceeds the individual anime episodes.

Honestly, I would have been more read more
