Kuroko no Basket: Mou Ikkai Yarimasen ka

English.
Without a doubt I love these types of episodes, they show us a different side of this boy's rivals, who they were and what happened to them to get to the point of who they are today.
Here we see Aomine's point for me, one of the most interesting in the series and at the same time detestable, I always hated the way in which he didn't care about anything, but here they show what a good person he can be and was, they show us how they discovered the Kuroko's hidden talent and how he was used for the team, something interesting to discover in ... the series, how someone from being a substitute became one of the starters.
If you have the opportunity to see this episode, see it without a doubt, you will not regret it, as it will give you new information, and you will also have a great time seeing the beginning of our protagonist and the beginning of Aomine's decline.

Sin lugar a duda me encantan este tipo de episodios, nos muestran un lado diferente de los rivales de este chico, quienes eran y qué sucedió con ellos para llegar al punto de quienes son en la actualidad.
Aquí vemos el punto de Aomine para mi uno de los más interesantes de la serie y a la par detestables, siempre odie la forma en la que no le importaba nada, pero acá demuestran lo buena persona que puede ser y fue, nos muestran como descubrieron el talento oculto de Kuroko y el como lo emplearon para el equipo, algo interesante de descubrir en la serie, como alguien de ser un suplente se convirtió en uno más de los titulares.
Si tienen la oportunidad de ver este episodio véanlo sin lugar a duda no se arrepentirán, como a mi les dará nueva información, además se la pasarán bastante bien el ver el comienzo de nuestro protagonista y el comienzo del declive de Aomine.

It took me some time, but for the confused, here you go. This is episode 16.5 from the second season, a backstory episode that delves into the relationship between of Kuroko and Aomine, how they were and how they became. Aside from the drama and setup, it feels like a chill and very cute episode, showing the OG Generation of Miracles team, I believe, it's even the first time Akashi is shown to be active in a game. They all look very young and middle-school-esque for the first time, something that really bugged me whenever they would show a related backstory on the parent show.

So this is another OVA of the famous title, huh? Mmm, cool, you probably think if you're a fan. Must be average, you rather think if you aren't. And I'd say yes, this is middling. But, it's a strong one.

This episode tells us about Kuroko's beingness at the time of Teiko and how he managed to overcome his weaknesses. It also covers prehistory of Aomine's demeanor. On the plus side here — it's a long-awaited piece of the story, that makes it more interesting and clearer, with no apparent flaws. On the minus, it makes no advances as well: same art, same sound, and of ... course the same OP-ED That's all, can't say more avoiding spoilers) But it's quite interesting, so this one is to check out for every fan of the series
