Stellar Blade and Bayonetta have announced a crossover collaboration, with director Kim Hyung-tae publicly praising the Umbra Witch series as one of his favourites and crediting it as inspiration for creating Eve. This marks a notable convergence between two prominent action game franchises, with PlatinumGames CEO Atsushi Inaba recognising the potential value of such a partnership and expressing openness to future collaborations between the studios.

During a Famitsu interview, Kim expressed enthusiasm for potentially contributing to a future Bayonetta game, jokingly stating he would work at PlatinumGames daily if given the opportunity. Inaba praised the faithfulness of the Bayonetta-inspired costume designs in the Stellar Blade crossover, noting that Kim's work strikes a balance between authentic Bayonetta aesthetics and Stellar Blade's own style, with both companies reportedly welcoming further collaborative initiatives.
