Anime “Tokyo Revengers” and the smartphone game “Kyouto Kotoba RPG Kotodaman” collaborated for the first time, and this begins from August 27, 2021.

The collaboration between the TV anime "Demon Slayer: Kimetsu no Yaiba" and the smartphone game application "Monster Strike" has started from Feb. 14, 2020. As a commemoration for this, the collaboration cafe has started on the same day in the permanent store of XFLAG, "XFLAG STORE" in Shibuya, Tokyo and Shinsaibashi, Osaka. Together with that, the original collaboration goods will also be on sales. The collaboration characters from "Demon Slayer: Kimetsu no Yaiba" that will appear in "Monster Strike" are: "Demon Slayer Corp. Member Kamado Tanjirou", "Water Pillar Tomioka Giyuu", "Bug Pillar Kochou Shinobu", "Kibutsuji Muzan's Lackey Yahaba & Susamaru", "Drum Demon Kyougai", and "Lower Moon Five Rui". As Tanjirou can use both the "Breath of Water" and "Hi no Kami Kagura", his element will change from water to fire after Divination. Even the logo used for this collaboration had shown Tanjirou with 2 different elements and the motif of the cross over between "Breath of Water" and "Hi no Kami Kagura" was used. Furthermore, as a commemoration for this collaboration, the collaboration cafe is held at XFLAG's permanent shop, "XFLAG STORE SHIBUYA", and "XFLAG STORE SHINSAIBASHI" from Feb. 14 until Mar. 1. Various collaboration exclusive menus based on "Demon Slayer: Kimetsu no Yaiba" such as "Do you best! Eat this don and get stronger!", etc. are available in both shops. Collaboration original goods such as "Choose-able Tin Badges (Total of 6 types)" will be on sales as well. Further information on the collaboration limited menu and original goods are available at the special page in "XFLAG STORE". (C) Gotouge Koyoharu/ Shueisha・Aniplex・ufotable
