I'm unsure where you learned this English rule. The title is incorrect but not the comic. "Has" is the verb in the comic. "Effect" is used as in cause & effect. The only time in English "no" is used in front of a verb is when the verb is a gerund, ie "There is no running in the halls" when the verb functions a noun. Otherwise, "not" is used in front of verb. ie "This is not affecting you"
