Sure thing. Here are the characters involved:

About the order of events, it's been exactly the same up to the first colosseum event (the one with Amor, Vanya), so that's why I was surprised when after it they put out the dungeon event (the one with Typhon, Forcalor), skipping 4 events. You can quite notice that from how Typhon shows much more power creep than expexted and is placed in the album after a lot of pages from Amor/Vanya. Probably they just wanted to put the dungeons in ASAP? It seems they're running it backwards now, the current raid event (Dai Toren) is the one immediately before the dungeon event. If they keep going backwards, next is a colosseum event then it will be the Halloween raid with those lolis... if they're making it. The character release order has been quite different compared to DMM too.

(Oh, by the way notice how this game is called "Crime Busters" on DMM and that makes more sense than "Duel Squad", at least to me)

Hmm, I went and checked so let me explain better... first, the first loli was added to gacha pool some time after Crime Busters launched. And after the first colosseum, it was mid-october and they made a Halloween themed event. The Halloween raid event was in two parts. The first week the second loli (Which is actually the [Halloween] version of the first one) was the UR reward together with this SR. The second week had no loli rewards: [Halloween] Lysette doesn't count because of her enormous breasts I suppose.
The third loli was a slayer UR added to gacha pool for the following colosseum event. After that, they had the sisters raid event we're having now, and then the Dungeon event we just had.
