Penguindrum - Season 1 Episode 20 Thank You for Choosing Me

Masako decides to leave the Takakuras alone, still not accepting the 'family' they have. As Himari has another conversation with Sanetoshi, Shouma confesses to Ringo that Himari is not actually his blood sister. Years ago, whilst his parents were organising to change the world with their organization, Shouma met the orphaned Himari whilst exploring his condo. Whilst she is initially passive of him, the two grew a friendship over an abandoned kitten they find, up until it ended up being taken away. When Shouma discovered that Himari had headed over to the 'Child Broiler', where unneeded children go to disappear from the world, he rushed over there to rescue her and chose her to become a part of her family. Back in the present, Kamba continues to converse with his parents about what needs to be done to change the world.
