15. Yuukei Yesterday V

'''Kagerou Days 15. Yuukei Yesterday 5''' (カゲロウデイズ06．メカクシコード 3) is the fifteenth chapter of the Kagerou Days Manga.

Summary
Haruka is now interested in shooter games, after Takane's performance, and aspires to be in the tournaments. However, he suffers multiple attacks and so cannot enter. At one point, Haruka and Takane are discussing names, him noticing Takane's way of naming herself with the letters of her surname and first name, and similarly naming his character Konoha. Later, Haruka and Takane are working together during the summer. Haruka states that he gets to play shooter games because he had already finished his work, and Takane wasn't done yet. Takane, unpleased, puts on her headphones and pretended to ignore him. However, Takane looks over and realizes that he has an attack, blaming herself for it. The chapter ends with her pleading for Haruka's sake.
