INFORICH's 'CHARGESPOT' Partners with Manga 'WORST Gaiden GURIKO' for Exclusive Collaboration in Kyushu

INFORICH Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; Representative Director and Group CEO: Hironobu Akiyama), the operator of the mobile battery sharing service 'CHARGESPOT™', and Akita Shoten Co., Ltd. (Headquarters: Bunkyo-ku, Tokyo; President and Representative Director: Tokuji Yamaguchi) have announced a special tie-up with the popular manga 'WORST Gaiden GURIKO' set in Kyushu. This collaboration is aligned with the 'Kyushu Region-Exclusive Pricing Test and Large-Scale Promotion' starting on Monday, June 15, 2026.

With the shared goal of revitalizing Kyushu, the setting of the manga, the two companies will carry out a powerful cross-media campaign focusing on 'CHARGESPOT' digital signage installed at major convenience stores in the Kyushu region.

Background: Shared Goals to Revitalize the Kyushu Area To verify the optimal pricing structure for future nationwide rollouts, INFORICH is launching a strategic pricing test and large-scale promotion across the Kyushu region to lower the psychological barrier to renting batteries. To promote this new challenge originating in Kyushu, the company partnered with 'WORST Gaiden GURIKO' (illustrated by Ryuta Suzuki, based on the original work by Hiroshi Takahashi). The manga, a spin-off of the highly popular 'WORST' series, depicts the wild middle-school adventures of protagonist Guriho Hanaki in Hakata, making it the perfect partner for this campaign. By fusing the infrastructure of CHARGESPOT with the energetic spirit of the manga series, the campaign aims to energize the streets of Kyushu.
