"How is it?" asked Anko with her innocent expression.
"The way by making a coil on this flat object, this is a real painting medium." Obviously Mafu, but is it true how to use energy? He's not sure.
"Hmm... Can it be done with ink?" asked Anko. However, Mafu seemed to disagree.
"Hmm, unfortunately there is no ink here and if you use it it must be quickly erased." Obviously Mafu earnestly.
It's the same with kuchiyose: To summon a spirit of the deceased, it takes a high level of energy, and blood contracts, as well as keywords that correspond to it.
Could this work?
"Ah! Mafu, I remember!" quipped Shin with a cheerful face.
"Then we use blood!" said Anko seriously, "You want to call an earlier king, right? Surely using blood will work because it won't be able to be removed." He gave a good explanation.
Instantly Mafu remembered, usually the summoning move was like that.
"Oh, yes, yes." Mafu agreed.
