Ryuko Matoi (partnered with Gau, that poor kid):
- also pushed most of the work onto her partner
- saved Gau from strangulation via force and yelling at the baby
- taught the baby how to swear
- threatened to beat up anyone who touched the baby
- ... then threatened the baby herself
- barely avoided throwing it into the wall after a sleepless night
- somehow managed to not kill the thing, though that's more thanks to Gau than her
