Occult Gacha Verification (?)

I was pulling the distributed rerun gacha tickets one by one and got Kirari Ryuseigun, so I went for the Pissaro gacha with mileage. Apparently, serious players recommend skipping this gacha, but I don't have any "tension-lowering" weapons, and I thought the swimsuit looked pretty cute after changing my hairstyle, so I aimed for it... Does "Nakamon" probability increase!? And it's non-duplicatable, ah... Since there's one accessory slot left, those who are particular about "Nakamon" might need at least one armor piece (for those not fixated on Nakamon).
