The Wheel That Spins Us Round
Kanba goes home and is called by Sanetoshi claiming that Himari will die once more. Shoma goes into detail of what happened 16 years ago, as Shoma and Kanba's parents were high ranking members of a terrorist organization and were responsible for a terrible incident which killed Momoka. Himari still possessed loses her strength and tells Shoma and Ringo to acquire the Penguin Drum and to stop "them". Himari is then transferred to an hospital and Kanba is called by Shoma. He arrives to find Himari lying dead and tries to once more make a pact to give her his life, but it does not work as she says she must leave to "The Destination of Fate". Just as Himari seems to be truly dead, Sanetoshi appears.

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!
