A great historical family drama, with some excesses that I wish I were spared but still a great work in its genre.
What I appreciated the most was the historical setting, probably among the best I've ever read in manga. The atmosphere is cared for and while reading I really felt as if I were living in Japan during the Taisho period. The beautiful background art played an important part in this.
The family drama was interesting and full of plot twists, but also a bit too much for my taste. Basically NOBODY was mentally sane and at some point it started looking fake (could have done without "Sakurako-sama" ). I wish the whole Souma family drama was a bit less over the top, like Masataka's personal history, which felt truer to me. Although I do acknowledge stories that sound too weird to be real do exist in our world, especially when it comes to trauma and abuse.
Speaking of abuse,
I think the mangaka cleared why Souma raped Masataka. Because of how he was treated by others, Souma always thought of himself as not deserving to be alive - but Masataka saw the good in him. Souma wanted to believe in Masataka's idea of himself, and become a good person. When Masataka discovered the pictures his idea of Souma collapsed, and so did Souma's hope to be a better person. He felt rejected by Masataka, and fell back into being the horrible person others always made him out to be. It was the same old self-fulfilling prophecy he was living in for most of his life. "If, after all, I cannot be the good person Masataka thought I were, then I might as well be as evil as everyone thinks I am, and get what I want no matter whom I hurt - my connection with Masataka is broken anyway" something like that. It makes sense to me that he ended up abusing Masataka - having he himself been abused throughout his life, in one way or another. However, I think having him rape Masataka again and again was just too much. Masataka forgiving one rape because he understood it was the action of a broken man who was himself abused would have made sense. But forgiving countless sexual assaults and horrible abuse? I don't know...
If you can forgive these excesses, though, Sakura-gari is a beautiful story of sorrow, sin and redemption, definitely one of a kind among BL series.
