Sanae Dekomori (凸守 早苗 Dekomori Sanae) is a side character from the Japanese anime, Chūnibyō Demo Koi ga Shitai!. She is voiced by Sumire Uesaka in the anime.
Sanae Dekomori has been Rikka Takanashi's friend since they met each other two years ago via internet. Similarly to Rikka, she is also suffering from eighth grader syndrome. She has long twin-tails tied with small weighted bags that she calls "Mighty Mjolnir Maul" that "makes men meet their mortality". She hates milk very much but still forces herself to drink it everyday, hoping to grow taller. She is very prone to motion sickness.
A year ago, Sanae posted queries about parallel worlds on the internet. She received replies from the “Tyrant’s Eye” and “Mori Summer”, which delighted her. She later found out that the “Tyrant’s Eye” was her "master" in a "previous life" and decides to become her "servant" once again. She is trying to seek out “Mori Summer” which Shinka Nibutani later revealed to be herself; however, Sanae does not believe Shinka and so she always addresses Shinka as “Fake Mori Summer”. Sanae is very intelligent and has the best scores in her whole grade. At the end of the series, she is shown to come from a wealthy family, in one instance arriving at a location in an upper-class sedan with a butler in tow.

She has very long blonde twin-tails tied with small weighted bags that she calls "Mighty Mjolnir Maul”. She has blue eyes and can be considered short. She hates milk and other dairy products. She respects her master, Rikka but does the opposite towards Shinka. She is quite popular in her class because she has excellent mathematical abilities. She has already finished the middle school math curriculum and can solve high school questions easily.
