In honor of summer, Idea Factory International has released swimsuit costumes for each of the girls in Death end re;Quest for free. These can be found here for the PlayStation Store and Steam.
This comes as a bit of a surprise, since Death end re;Quest released a few months back and focus is on Dragon Star Varnir. Given the news that will also see a PC release, hopefully this is the first step in seeing more of this DLC being early adopter based than limited to paid.
