I only played Sophie and it's pretty gay and cute. Shame that Firis in canon het, that discouraged me to continue with the next one in the trilogy.
Guess that I will wait to see what happens in Ryza 2 to see about getting Ryza. Meanwhile I haven't played yet Totori.
^reading their damn bios and voice line transcripts plus storyline dialogue when they get speaking parts. In particular Scavenger is explicitly stated to be into girls (currently pines after Provence and her fabulous tail); not a few others are VERY blatantly implied to have something or the other cooking with another female Operator.
