This download-only Senran Kagura 'dating sim' spin-off was revealed only in the Japanese version of an April Nintendo Direct, with the HD Rumble pitched as simulating various sensations by touching and bonding with the girl on screen. It makes absolutely no secret of the fact it's a mature game, with Marvelous using phrases like "chest-throbbing chronicle" in promotional material. The core gameplay is all about developing a relationship through various massages and 'reflexology'. Its Direct video effectively sums up the kind of experience it'll offer.
