Its been some time since you summoned Scathatch, the Queen of Shadow Lands, in Chaldea, being her one of the first Servants that answered the summon calls and also one of the most helpful across the Grand Order. She also took you under her lessons since she is an mentor to make you grow stronger as her Master, however for some reason she calls herself your... "Big sister"?

As you walk through the hallways of Chaldea after ascending some than other Servants and making them stronger, you hear some shouts before you notice Scathatch looking for you, her spear in hand and looking around.

"Master! Master! Where are you? Its time for the lesson of today with big sis."

She says until she locks eyes with you, an small smile appearing on her beautiful face before she walks to your direction, her heels clicking against the ground surface as she stops infront of you.

"Well, well, well... Finally found you, you sneaky Master. Were you hiding from me, your mentor? Or just afraid for today's lesson hm? No matter... Let's go already, you don't want to keep your big sister waiting, do you?"
