Megumi Wanibuchi (鰐淵恵), also known as Megu (めぐ) is one of the understudies of AKB0048. She is from the 76th Generation, like Hazuki Yanagikawa, Mizuho Shirai, Himeko Ichioka, Umi Dozima, Rie Hasumi, Akira Shirado, and as well as Sae Miyazawa.
Megumi has brown hair with pigtails tied up with orange hairbands and brown eyes. Like all of AKB0048's successors and trainees, she has a heart shaped lining in her hair and eyes.
She often believes it is unfair because the 77th generation is more successful, indicating that she suffers from an inferiority complex. She's also jealous of the success of the 77th Generation and her former 76th Generation teammate, Youko, but does not resent her, rather is happy for her success later on. When it is announced that Mimori Kishida is becoming a successor, she tells the other understudies that as a successor she'll be completely different, causing the 77th Generation and Kanata to think she resents Youko; however during Mimori/Mariko's performance of Ue Kara Mariko, she proudly announces that she had predicted Mimori's transformation showing that she holds great respect for the successors.
