Thank goodness the immortality drug is still incomplete I hope this drug is never completed, it would be horrible if they don't die in the end (Rentaro with 100 years or so)
I mean there is an anime that it's about this exact plot:
Bludgeoning Angel Dokuro-chan tells the story of 14-year-old junior high schooler Sakura Kusakabe, who twenty years in the future develops a technology that causes all women to stop physically aging after they reach twelve years old in an attempt to create a "Lolicon's World". However, this act accidentally creates immortality amongst humans, thus offending God. Dokuro Mitsukai, a member of an order of assassin angels that are called Lulutie, has been sent from the future to kill him.











Just two weeks now, the movie is coming and the trailer is awesome ヾ(☆▽☆)
