“Alya Sometimes Hides Her Feelings in Russian” (also known as Roshidere) will celebrate its 5th anniversary with a special event, “5th Anniversary POP-UP School,” held at Yurakucho Marui. The venue will feature anniversary-style exhibits that let fans look back on the series through visuals, including a gallery of high-resolution reproductions of the cover illustrations that have colored the novels and related books, as well as a character wall showcasing memorable artwork alongside quotes.
In addition, newly drawn illustrations will be used for commemorative merchandise, and purchase bonuses will be offered depending on how much you spend. A major highlight is a double autograph event with both the author, Sunsunsun, and the illustrator, Momoco. Since participation is by lottery and requires meeting entry conditions, it is a good idea to check the application window and requirements early if you plan to attend.
