源頼光
Tsuna showed the oni's arm to Minamoto no Yorimitsu. Yorimitsu consulted with an onmyoji (there are versions where it was Abe no Seimei, who said that "the oni will surely come for its arm, so confine yourself in your house for seven days, and don't let anyone in the house for that time". Several days after that, Ibaraki-dōji tried to invade Tsuna's estate using the remaining arm, but due to the power of a Humane King Sutra and a talisman, Ibaraki-dōji was not able to enter.
