- Unsurprisingly, this trope is initially parodied in Chapter 43.
- It's played much, much straighter, however, with Hilda's Heroic Sacrifice.
Hilda: The Master is now in your care. You're the only father he has in this world...
- And again in Chapter 141, as Hilda cries over how Oga keeps on insisting that she needs to get her memories back and refusing to accept her as she is.

- Chapter 231: Two words - "Da da."
- In 236 Kunieda call Oga out for his real reason for not calling Beel back that he secretly fears Beel loves Iris more than he loves Oga. Then Kunieda is turned to stone while still yelling at him.
