Life continues as ‘normal' for Birdy and Tsutomu. Though they still co-exist in the same body, Tsutomu is able to focus on his studies while Birdy keeps up with her celebrity job and Federation Investigator duties. However, things become more complicated when a transport ship housing prisoners connected to the Ryunka incident is hijacked. The aliens on board escape to Earth and blend in with the human population, and it's up to Birdy to capture them unharmed and escort them back to headquarters. Yet Birdy soon discovers that there are other forces involved, and it'll take everything she's got to bring these criminals back alive!

Tetsuwan Birdy Decode:02 As time goes by, you notice more and more which anime "Darling in the Franxx" was inspired by. And this is another one of them, as far as the second season is concerned. This season hangs right on the heels of the last episode, including the Ova and follows the new events from season 1 with a pretty fast pace, especially at the beginning. Honestly, I had high hopes for this season as it got off to a pretty solid start and possessed a pretty interesting implementation and portrayal of the vigilante theme. Together with the new third protagonist of this season around which the story revolved, this was on the whole an interesting plot. Unfortunately, until about episode 8, everything after that was boring, stretched out, and covered with an absurdly stupid finale. Seriously? Of all the things you could have done, you chose this paradoxical decision? And then with such a bad implementation and explanation? That was even more of a failure at the end than "Mirai Nikki". Of course, this spoiled the whole positive build-up of the season, although I would have liked to say that this season was better than the first. It was superior in terms of faster pacing, better writing, and characters. Story [5] And here's where another problem has been. The entire story arc was only connected to revenge, on the masterminds of the first season. Otherwise, it dealt with nothing more than the various ambitions of the characters. But thanks to the much better execution than in season 1, this had been presented very creatively. Unfortunately, the finale to which everything boiled down was quite a disappointment. "Time" is a dangerous topic, especially if you can't properly implement it in the plot. Because of this poor approach, everything that was built up for this finale was naturally ruined. Characters [6] Honestly, this surprises me, but I couldn't give this season fewer points. Not only did we see a very understandable presentation of revenge and vigilante justice. But also many character conflicts and developments, especially between the finale of the first season and the transition to this one. The protagonist learned and developed through his mistakes so he could help Birdy with the same problems. Kind of ironic, isn't it? First, he was the problem child who couldn't accept the truth and wasn't aware of his feelings and now the roles have reversed. The antagonists this season have unfortunately been very empty and had almost no screentime nor real ambition. The only thing they had was a hateful personality so that you would feel a "good feeling" as soon as their karma reached them. My favorite this season, however, was a new character that everything revolved around. His calm yet impulsive personality and a strong quest for justice made him completely understandable and relatable. Animation [6] Predominantly subtle in the day-to-day and increasing in the action. This dynamic style of animation is atrocious in terms of detail, all you see are stone blocks flying around and characters playing Twister. However, they have been very suitable for larger stage changes in the battle scenario, as well as the choreography of the fights. Music [6] The intro...I kept having Darling in the Franxx flashbacks, help? It was musically satisfying, as well as visually. On the whole, neither an earworm nor a major recognition value is present, just as with the outro. Only a few osts have been stimulating and interesting. Conclusion I don't know the manga, but after a quick check, I noticed that there are significant differences between the manga and the anime already at the beginning. Therefore, it could be that the flaws in the work are "Anime Only". Unfortunately, I won't know and since this season has an open and unfinished ending, it will probably be the same for many. It was a decent anime for in between, which had good approach but failed in a meaningful implementation. Enjoyment - 5]


Plot:Usually sequals tend to be worse than the originals, but, Birdy the second season manages to flip that theory compeletly upside down.The sequal focuses much more on Birdy. Tsutomu probably appeared for a full fifteen minutes (or less) if you combined all the scenes where he was in. The main focus is probably Birdy's relationship with Nataru and their pasts, and this time, there is no "saving the world" thing going on. It's on a much smaller scale when it comes to that. Of course, there still are "bad guys" although, you start having doubts on how evil they are as the series progresses.What I really liked about this series was that action moments were interwoven with slice of life elements. They both complemented each other. Their purpose for fighting expanded their character dementions and left you on the edge of your seat. Characters were shown that had little to do with the series, but still showed how they were living on after the drastic destruction that took place in the first series. Animation:It can get weird at points, but other than that, it is nothing short of astounding. The fight sequences, the scenery, all of it is breath taking. You should definitely watch at least a trailer of Birdy, just to see how amazing the animation is.Sound:The soundtrack is significantly better in the second season of Birdy, even though it was also very good in the last one. I actually have the soundtrack on my iPod, that's how amazing it is. It fits very nice with the story and scenery and sets the right tone that evokes emotions more powerfully.Characters:Birdy really comes out in this series. A lot is revealed about her and her personality, and the relationship she establishes with Nataru, is a delight to watch. Almost all of the characters you meet are memorable, and sometimes confusing (you'll see what I mean if you watch the series). There are twists on the characters personalities that lead you to second guess them.Overall:Watch it. It's another one of my favorite series, and I'll probably go back and watch it in the future. It's series like these that don't make me lose faith in anime. It gives me hope that there are still gems amidst the over abundant modern crap, wating to be found.


Decode 2 is a direct continuation the first season and picks up after the events in the Tokyo Bay area that resulted in widespread death and destruction. The series opens with the capture and subsequent breakout of the terrorist group responsible for the Ryunka's theft. After a violent escape by the terrorists, Birdy is contacted by the Federation and informed that the terrorists are now in hiding on Earth and is ordered to apprehend them. The second series delves more Birdy's past and the geopolitics of an interstellar community, as members of the Altaran species have been discriminated against for supposed terrorist actions they comitted against the Federation. Matters are complicated when one of the terrorists turns up dead, setting her on a course that will bring her face to face with her past. Despite the violence of the opening and the mature overtones of the subject matter, Decode 2 tries to maintain light harted appeal, interspersing action and intrigue while mainting the comedy and drama of an everyday life of two very different individuals. While not a major hindrence to the overall story, some of the transitions between segments give the series something of a disjointed feel in its tone and bogs down the progression of the story. The animation in the second season suffers in both detail and quality, with some action sequences becoming colorful smears of surrealist art and confusion. The story preceeds rather predictibly throughout the second and third acts, with the original plot thread carried over from the first season (namely that of Segawa returning to normalcy) ultimately becoming buried in favor of the pursuit of examining Birdy's past and the hunt for the terrorists. The unfortunately leaves the ending completely open, with what we can only assume will be a third season.
