+Tic Elder Sister (Japanese: ＋チック姉さん, Purasu Chikku Neesan) is a Japanese manga series written and illustrated by Cha Kurii. It has been serialized in Young Gangan magazine since September 2009. The story revolves around three high school girls in THE City's THE High School - Iroe Genma, Hazuki Okamoto, and Makina Sakamaki - who are members of the model-building club and each wear a model on their head. This school comedy manga is known for its exaggerated humor, absurd storylines, and distinctive characters. The manga later transitions the club from model building to calligraphy, and the girls discard their head models. Additionally, two spin-off manga series, MeMeMeMeMeMeMeMeMeMenhera... and Aoikokoro ga chikyū o waru, have been published. A twelve-episode original net animation (ONA) produced by TYO Animations was released from 2011 to 2012. The first five episodes were available online, with the remaining seven included on Blu-ray and DVD.
