well, assuming you mean 120 galaxy bookmarks (which i assumed based on your 4000 mystics; no way you did 4000 mystic summons), you shouldnt have expected to get a ml nat 5 anyways since the chance is 2.7%, yet you only did 24 summons... and yeah, it might seem unfair, but thats why the 121 club exists - which im part of. Thanks ss bellona. players should expect to get a ss bellona every 100 summons on the banner. but such is life.

"not a single four star" and "every four star I summoned"
You did summon 4 stars, why are u complaining? I summoned a Dupe 5* but whatever man, some people get unlucky.

summoned 6 wandas in 14 ml pulls and on my mystics I had a repeating pattern between hazel and mighty yashka(repeated 4 times), while having a plethora or 3 stars at the same rates this shouldn‘t be possible at all.
