Trivia

 * This chapter appears to be a reference to the anime's 19th episode, where similarly Shiemi wants to throw a party (although it's originally for Izumo before she demands it to be a party for everyone, and it's a birthday-only party, not a Birthday-Christmas party) and Rin also gifts Yukio with disguise glasses.
 * Yuri Egin's appearance is also somewhat reminiscent of her anime appearance.
