I got Bass and Hikea from Epic Pachinko. Their 0 star design makes me sad and after looking at the 1, 2, and 3 star designs, I can safely say I wouldn't mind not having them.
I also wish I didn't get one of my favorite girls, The housemaid, at girl #35. Now it'll cost me around ~4.4m to upgrade her to level 3. Regine is the 14th girl in my harem and would only cost me about 1.6m. I wish that Regine drop was a The housemaid drop, but I'm still happy I finally got her.
And I'm sorry but in my view, I can't find anything that I like of these two...
I got them during Winter Chill. I could have gotten Viola or Winter Sophie (both of which I really really really wanted). If I could trade these in (I'm just ranting out loud now) I would want either Notka, Sailor Celsius, Skytte, or Vissihar. Luckily I already got some girls that I already wanted, like Lupa, Sporty Noemy, Princess Tiana, and Empress Tsubame!
