|Acting Completely Serious Technique|
Mattaku Boke nai no Jutsu
Acting Completely Serious Technique (まったくボケないの術, Mattaku Boke nai no Jutsu) is a technique where Orochimaru simply puts on a serious look on his face. This technique is design for a character to not play the role of the straight man.
- Orochimaru made this technique specifically for Tenten and ironically proved effective.
