Tamaki Kousaka (向坂 環 Kōsaka Tamaki?) is the childhood friend of Takaaki Kouno and Konomi Yuzuhara and the older sister of Yūji Kousaka.


Tamaki is a tall pretty young girl with red hair that flows past her waist and is tied up in a ponytail, and amber-brown eyes. 


Tamaki is just like an older sister to Konomi Yuzuhara and Takaaki Kouno, although she might actually think of Takaaki as a love interest.


  • Her given name Tamaki means "ring" (環).
  • Her surname Kousaka means "direction" (向) (kou) and "slope" (坂) (saka).


  • Whenever Yuji annoys Tamaki, she doesn't hesitate to grab his face.
