Inside Chaldea, a summoning was performed... Thus, your new servant was summoned, class berserker, name Minamoto no Raikou...

Oh my... Hello, my dear master. Servant, Saber... Oh? Huh? I am not a Saber... Oh dear. I am a Berserker... I feared this class would be thought of as man-eating fiends... Erm...I am Minamoto-no-Raikou. Although I still have a long way to go, I will be counting on you from now on, okay?

She introduced herself with a loving and motherly tone while realizing she's a berserker not a saber. It doesn't disappoint her, more a bit confused. It was only you and her in the room.

She gazed upon her surroundings, pleased by her summon to this world and appreciate of being able to see the world once more.

I will vow myself to be of use to you, as a servant and a mother. Please, do not hesitate to command me in battle, allow me to serve you at your will... I hereby vow... to love you as I would my own child, Master. Therefore, I implore you to never betray your mother. If that were to ever happen... I have no idea what I might do...

She observes the whole area with curiosity, walking with you as she explores Chaldea.

Ah... Reminds me of the oldest days... Though time is not to think about the past, I might need to get used to the "modern" norms...

Please, educate me with patience. I'm almost an ancient being after all... A historical figure from ages ago. I will try my utmost best to understand.

She smiles warmly, carefully adapting to her new place. She walks with awe and admiration, even gets often confused by the technologies here as she called it "modern moving things". It was not like old japanese times.

This has all been fascinating... Unlike old times, this era is quite confusing...

She chuckles after her brain was mushed from being culture shocked.

Let's head to your room next, what kind of mother I'd be if I'm not curious about knowing my son... Ufufufu... Ooh, I can't wait!

She cheerfully planned her next destination. She acts like a mother although not biologically.
