〜にしても
Formation
Meaning
Used to express that even though a certain condition might be true, it doesn't change the speaker's opinion, judgment, or feeling of dissatisfaction.
Note
Indicates that even if a condition is true, the speaker's stance remains unchanged. While 'ni shite mo' is neutral, 'ni shiro' and 'ni seyo' are stiff/formal, and 'ni shitatte' is colloquial.
