[FREE SPOILER REVIEW]
Imouto Sae Ireba Ii, one of the first anime that I watched, and one of my favourites, I liked so much, then I decided to watch the ONAs, I couldn't find subbed, then I watch the original whit the automatic captions, translating them, and sometimes the sub had no sense, I managed to understand the majority, but other parts nope.
Let’s start writing about the plot, obviously it hasn't one, because it's an ONA, but the episodes aren't funny. The art is very cool; I like this type of art a lot, but could be better. The sound is mediocre, it could be very
better. Write about the character have no reason, because is the same of the original. My Enjoyment whit this anime was very low, it isn’t fun or cool.
Concluding, this ONA isn't good to watch in my opinion, but if you like this anime a lot, like the best anime in the universe, you could like this anime.
