The story this far is pretty much same as LN and anime version.
Players who knew the series and just want to enjoy it can give this game a try, but for those who search for a challenge and something similar to it, i'm afraid you'll be disappointed 'cause the gameplay is basically auto-attack while player just waiting for skill bar to fully charged and tap the respective character to unleash the skill (=・ω・）ノ
but the only problem is the londing srceen is too slow
it's always shows the Network Error
I hoped it will fix in the next Update
keep up the good work ♡
