The official website for adaptation of Watashi ga Motenai no wa Dou Kangaete mo Omaera ga Warui! (WataMote) by Nico Tanigawa, revealed the designer for the 3 main characters.
Below you can check out the WataMote characters!
Tomoko Kuroki, a girl who thought she would be popular when she entered high school , realized the loneliness of reality when she couldn't find a boyfriend or any friends within two months of the opening ceremony. She doesn't stand out in her class and has trouble talking to others.
Tomoki Kuroki is Tomoko's younger brother, and he's in middle school and a starting player on the school soccer team. Unlike Tomoko, he has many friends and is very popular with the girls. He's often irritated and acts cold and negative toward his sister, but he also has a gentle side.
Yu-chan is Tomoko's middle school classmate. She gets along well with Tomoko because she shares the same hobbies, but they ended up separated and going to different schools. She used to be a sweet middle school otaku, but it looks like a lot is about to change.
The anime will be released in July in Japan.
