Null is a young genius who misses her older sister, Peta… so she decides to re-create her, using her incredible intellect. The results are not exactly what she anticipated.

Peta makes her specialty dish for Null’s breakfast, but even before she was a robot, her cooking could be questionable. It seems like the added processing power and machine strength haven’t done anything for the older sister’s skills in the kitchen.

Peta wants Null to attend school, but Null’s advanced intellect makes her stand out from her peers. Can the siblings come to terms over Null’s class attendance?

Space: the Final Frontier. Null has found herself stranded in the vicinity of an abandoned space station in Earth’s orbit, unsure of how to get home. Will Peta be able to save her little sister?

Null and Peta head to the beach where Null meets a new friend.

Peta seems to be up to something that might be putting her in danger, so it’s up to Null to follow her incognito and discover the truth.

It’s an invasion! The town has been swarmed by tiny ravenous bugs that are intent on eating everything in sight! Will Null’s scientific know how and Peta’s robotic power be enough to exterminate the scourge?

The tiny bugs that eat everything aren’t so tiny anymore, as they fuse together into a giant entity intent on eating everything in it’s path! Can the sisters stop it before there’s nothing left to save?

Peta has vanished, leaving Null to wonder where her big sister has gone.

Null has discovered something unsettling, and with Peta still missing, she’s left alone to ponder the magnitude of her realization.

Null and Peta are reunited, and the sisters resume their life after the changes they’ve been through.
