Blame!/Heartwarming

In the fifth volume, we see into the nature of Mensab's and Seu's relationship. She is quite affectionate and fusses over him each time he is resurrected and she is unable to recreate him fully due to the President's restrictions on his data, much to her frustration.
Cibo waiting for Killy for ten years after the teleportation incident. Not that she had any other choice, but the dedication is somewhat touching if you stop and think about it.
The fact that Killy and Cibo stuck around with each other at all is probably a CMOH in itself.
