紅茶のティーちゃん登場です。生放送にて皆とデザインして決まりました！
カフェちゃんがあの胸だったのでティーちゃんはこの胸になるのは必然だったかもしれません。

Tea-chan, from black tea, makes her appearance. She was designed with input from everyone during a nico nico live broadcast!
Since Cafe-chan has breasts like that, it might have been inevitable that Tea-chan's breasts would be like this.
