I'm really liking the way the story is going. There's huge potential here and really want to see more of it. Haven't read a refreshing onmyouji story in a long while. This can grow into a big thing.
Dare to bet, that birb paper will won't died and the option later was :
1. as joke relief.
2. 'somehow' can be used as catalyst of a god.
3. Evolved into shikigami.
4. can take more command and became smarter as the MC adding more diagram/spellcraft into it.
5. no shit, the most impossible. the birb became waifuable.
The "Did you notice" part of it, was probably Ki ga tsuita or some variation, right? @Ruukasu
If so: It isn't a "Did you notice", but instead "You've come to" (as in regained consciousness).
