Chapter 4
She is unofficially introduced in Chapter 4 by Yuri Nakamura.

Chapter 5
Irie joined up with the rest of the battlefront when they went out to eat in celebration of Otonashi's return.

When both Sekine and Irie heard how Iwasawa wanted to hear about Otonashi's life, they both put their heads down upon realization that Iwasawa may have taken a liking to Otonashi.

At the end of the night she chatted with both Hisako and Sekine about how Hisako wins her Mahjong games, though disappointed with her as she usually cheats to win. She returns home by getting a ride with Hisako.
