Sakura Kusakabe is a second year high school student who some time in the future will discover immortality for the human race. The messed up part is the immortality only works on women and since Sakura has a loli complex all the women stop aging at twelve creating a pedophiles world. This of course pisses off “god” so he sends angels back in time to assassinate Sakura ensuring the pedo world never happens.
Dokuro-chan decides that instead of just killing Sakura she can cause him to become distracted enough that he’ll never get around to discovering immortality. She does this by in fact beating Sakura to death with her “bat that can do anything Escalibog” only to use her magic to instantly revive him soon after. Rinse, repeat.
This is a short series that is a lot of fun to watch. After all, whats better that watching a cute angel beat some poor guy to death? Watching her revive him and do it all over again!
