“Then, I’m afraid I’ll have to trouble you, Saber. Draw two hexagrams overlapping each other on that spot, with a radius of six inches and facing this direction.”

“ – Understood.”

Saber also knew a bit about basic magecraft, so she could easily complete Irisviel’s demands.

Despite knowing the meaning of the instructions, she wasn’t clear on why Irisviel wanted her to do so.

“Then can you please mix some mercury for me? Strictly obey the ratios I tell you, and prudently – “

“Irisviel, I’ve got a question.”

Finally, Saber couldn’t bear it anymore, and spoke the question she’s kept hidden in her heart since this morning.

“ – You seem to be trying your best to avoid touching anything at all today; is it just me?”

“…”

“It’s like that for driving the car, or taking the keys… maybe such things can afford to be ignored, but you won’t use your hands even for the all-important magic circle; there must be some reasons behind it. Please correct me if I’m wrong, but is there something inconveniencing you today?”

Irisviel appeared like she’s having difficulties in talking about this, and glanced around. Saber kept asking.

“If you aren’t feeling well you should tell me beforehand. After all, I’m responsible for your safety, and I need to be prepared for such things.”

“… Sorry. However, I really didn’t hide anything from you.”
