- "Aunt Noriko? Tedd's mom?!"
- "First-born son"
NANASE - "Ellen! What does the scouter say about Not-Tengu's power level?"
ELLEN - "I can't hear you!"
NANASE - "What?! Nine-thousand?!"
WHOOSH
So, yeah. Unless Not-Tengu is mistaken, this comic confirms it: Tedd has at least one sibling. Annnnd neither Nanase nor Ellen are aware of this, because they can't hear him clearly over the rush of wind past their ears. Way to not overhear that you have at least one cousin you didn't know about, Nanase.
