I've reached above 110 lvl, played mostly Olivia, Samanosuke, Heriss respectively. I also got nearly 15 heroes like Eisha, Carin, Purity, Monica, Eric, Obsidious, Noctina, Polarus, Bandina and even Beldora . But unfortunately, when i broke up game a while and download back to play with dear olivia, i couldn't reach my account. Please it is really huge dissappointing for me.
If you know how can i learn id number, also reply for it then i would learn and repost. I really get back this account. Thanks
