So a few days back I have officially done I think 240 pulls on this treasure (If it's 120 scrolls per super) and received Gengetsu both times. Kinda wanted Rasa, so I am wondering does that happen only on this treasure? Because I know all other super rares alternate.

Pulling him (again): https://gyazo.com/c6daee4d7304f5e035eb97fd12aff629

Gengetsu (30 frags got 5 from events): https://gyazo.com/8f3ecfc9c9a00e4bc4dced093dedfa1e

Don't own Rasa: https://gyazo.com/6f007e707f34d4f2c3669c2ffebf9f9c

Gonna post this in customer service too, but likely get declined since I do not have a screen shot of my first super rare pull back when the treasure released (didn't pull him immediately when the treasure came out). The treasure has been out long enough for most people to either have a second super rare or be close to pulling it if you have played long enough. I know I probably won't get Rasa, but could one of you atleast test the treasure a few times to see if it is possible to pull the same super rare twice on this treasure?
