Is this a "V" reference?

Looks obvious to me.

With a brief search, I could not find applicable copyright tags.

I have no clue who Suwako is supposed to be, I must not know Peanuts as well as I thought.

If Kanako is Lucy, and Sanae is Linus, then Suwako is Rerun.

Yes it is.

Next question: Is the last panel a Keroro Gunso reference?
