You Have Finally Realized It
Kanba goes to confront Natsume about the memory-erasing balls and why she desires the diary, unaware that she only has half of it. Meanwhile, Ringo is still determined to complete Project M with or without the diary, making a love potion to give to Tabuki, which actually seems to work. As Ringo decides she can't go through with it, Yuri helps her come to the realisation that she is actually in love with Shoma. As Penguin Himari brings Shoma and Ringo into a Survival Strategy meeting, Himari tells them about the day 16 years ago when Momoka died and she was born, which turns out to be the day that Shoma and Kanba were also born.

Penguindrum
Once you make a decision, does the universe conspire to make it happen? Is destiny a matter of chance, a matter of choice or the complex outcome of thousands of warring strands of fate? All twins Kanba and Shoma know is that when their terminally ill sister Himari collapses at the aquarium, her death is somehow temporarily reversed by the penguin hat that she had asked for. It's a provisional resurrection, however, and it comes at a price: to keep Himari alive they need to find the mysterious Penguin Drum. In order to do that, they must first find the links to a complex interlocking chain of riddles that has wrapped around their entire existence, and unravel the knots that tie them to mystifying diary and a baffling string of strangers and semi-acquaintances who all have their own secrets, agendas and "survival strategies." And in order for Himari to live, someone else's chosen destiny will have to change. It's a story of love, fate, life, death... and Penguins!
