Love the hate here. :v I'll add some to it:
Never before have I seen such a Japanese protagonist, that after gaining an edge over everyone else by having memories of a past life, she immediately decided to use her understanding of the era to be a "low-profile simpleton", rather than throw a punch back at someone who fooled her to kill herself.
Behold the Japanese, who fold themselves 3,000 times backwards just so they avoid conflict. Remarkable Japanese Spine.
The plot's a mess, this one seems rushed.
