In the meanwhile, Monsterstrike is doing quite well on both Comgnet preorders and Amazon rankings. It'd be interesting to watch since it's basically a new IP in the handheld space.
I feel at minimum I'd consider it a popular licensed IP given 22 million unique downloads in Japan is a pretty astronomical proportion of the population.
Obviously they're trying to pick up a lot of younger children who don't have smartphones ye, but similarly may have awareness of the brand or played it on a family/parent's smart device.
