And... AND ! She is voiced over by the same person who does Victoria - Onibasu !
I genuinely LOVE that voice. (Plus I do love Victoria as well.... now now sweetheart, put down the axe, I just told the others how much I care for you.... siiigh... Yandere girls are quite ease to get along with if you know what makes their psychosis click, though its tiring mofu ~)
As Roentgen says, the easiest way to lvl up is to run the exp. mission.
I personally stuck with GS, I really like the game, the 2D animation of the characters, and the art style itself is VERY appealing, bunch of details and small things to take note of, something a person who pays attention to details when doing something does value.
Plus I got 3 Rainbows there my Tengu chan included, soo .... yeah, the game is great so far
And it has the best BGMs I ve heard in a browser game so far. Wish they add the option to listen to all of them or something, I vaguely remember the first or second event had some damn beautifull music. (sorry for the gramm. errors in this one, my spellcheck on Chrome aint working for some mysterious reason, and I am off to bed within next few minutes so my mental capacity is slowly shutting down for today.)
