"GirlsMons or Girls & Monsters: Angels of Terror (絶命美少女ギャルズモンスターズ, Zetsumei Bishōjo Gyaruzumonsutāzu, Deadly Bishoujo: Girls Monsters) is a Rare Cat Capsule/Gacha event that was added in Version 6.0 of Nyanko Daisensou. All Uber Rare members of this set come from PONOS' cancelled game GirlsMons. Version 9.5 added a Legend Rare Cat from the defunct game Kyoutou Project. This set also introduced multi-hit attacks to Cat Units, and it also seems to be the theme of this set, as all units have multi-hit."
