Senko is corrupting our youth.

Also, about page 8
"She means both words have three syllables."
You mean characters or kana. Chinko is obviously two syllables.
ちんこ
ペニス
Coincidentally, the explanation using "characters" and "letters" instead would still work with the romaji.
Chinko and penisu are both 6 letters.

@Anoon2323 Would she really even be Senko if she wasn't corrupting our youth? Just some food for thought.
