Tsukumonogatari (つくものがたり) is an adventure RPG for the PlayStation Portable developed by Killaware and published by FuRyu.

During battles, the player can send an e-mail from the mobile phone with a particular picture attached to it to summon the respective spirit to aid Yūto.

[2] Tsukumonogatari emphasizes the "power of words" as part of its battle system.

[2] One day, Yūto Ishigami finds himself pushed out of a classroom window by a fellow student.

Luckily, objects known as "Yorishiro" — everyday items occupied by helpful spirits — are strewn in abundance around the school as well, and these are the key to combating the Ayakashi invasion.
