So, finally finished reading the IC, and I'm pretty certain that I could not have asked for a better opening for a character introduction. I literally built my character to be the "tank" of the team, whose whole thing is being able to take the hits others can't.

So, fresh magical girl (with an admirable amount of confidence), enemy right on top of her that no-one else seems to be able to stop...

Couldn't have possibly asked for a better prompt.

So, Pros:
Character intros are mostly handled.
[b][i]Power of friendship intensifies.[/i][/b]
Nessie gets room to breathe and figure out what she can actually do (beyond having more confidence than God himself XD), along with an opening to potentially do something to this thing (considering it's been slapping around veteran magical girls).

Cons:
It's getting a bit crowded in this particular battlefield to be honest (but, to be fair, half the fun of this scene IS the hilarious amounts of overkill(?) getting thrown at the problem XD).
No potentially more personalized introduction for my character later, but that's not really an issue, when the whole point of this scene seems to be to establish the team. She doesn't need to stand out any more than she already will by just being herself.
Power of friendship not as good? (if Nessie potentially defeats it without any real aid or someone else snags her thematic new girl killing blow)

I definitely am leaning towards taking the opportunity for character intro, but I can wait for a later time if needed.
