Sini

**Sini Tamminen** (also known as **Agent 12**) is a Pacific Ocean Octoling created by LightningAgent5.

She is the younger sister of Lumi and Taika.

## Backstory

Sini was born in the suburb of Inkopolis, in the Inkopolis Empire. She, along with her sisters Lumi and Taika often played together with their cousins (Nana, Oktavia and Kanako), with their adoptive sisters Callie and Marie, but also with Sara, since the latter is her mom’s childhood friend, and often. At the age of 7, they met Alex/LA5 who wanted to gain his true form (his Octoling form) and live with Sara. Some moment later, while Taika and her family were going home, Callie, Marie, Lumi, Taika and Sini heard some screams. Taika, along with her mom, Callie and Marie were called for some help by Lumi who found a crying and scared LA5. LA5 then tells them that Sara and him were attacked by some humans and some Sanitized Octolings, who kidnapped Sara, and wanted to kill him too. Taimi then saved LA5 again and defended her daughters and LA5 against the Sanitized Octolings (who will be captured by Taimi, except the one who kidnapped Sara) and against humans (who will be all killed by Taimi). Callie, Marie, Lumi, Taika and Sini (her daughters) then asked their mom if LA5 can live with them (Taimi and her daughters), since he is alone and has no longer Sara to take care of him. Taimi then agreed (and wanted) to adopt and take care of Sara’s adoptive son, but LA5 explained that he has a (big) crush on the girls who saved him (Callie, Marie, Lumi, Taika and Sini). Taimi then tells him that she understands him and that’s ok he can live with them. At the age of 13, Sini, along with her friends, was recruited by her mom, Doctor Taimi Tamminen as Agent 12 (at this moment, Craig, along with Taimi and Hilja created together the Squidbeak Splatoon, but Craig was the 1st to recruit Agents), in order to fight Octavio's gang, and defend themselves, notably against this gang. Later, Sini, along with Marie, Kasumi, Alex, Kalina, Lumi and Taika went to save Callie, who was kidnappsed by Octavio. After Callie and Kyōko were saved (respectively from Octavio and Tartar), Sini, along with her friends battled Octavio again (because the later was Sanitized and then becomes more dangerous). Now, after the missions, Sini lives with her friends in a nice house in Inkopolis, near Octo Canyon.
