Gender identification and summer tags for this, post #8896323, and post #8896534 come from the equivalent pixiv ugoira uploads. post #4679637 probably has the same given I first saw all four in stills in https://twitter.com/itami_gomi/status/1416673716969250816, but it doesn't have an equivalent pixiv post (anymore?).

Medium tags for all four are from https://twitter.com/itami_gomi/status/1416836224891850752
