She seems easygoing and friendly. She is especially nice towards Ryuji, and calls him "Ryu-chan". The two are childhood friends, and she even embarrasses him by mentioning that he was in love with her and asked her to marry him.
She informs them that the blade can be repaired, but the method would require iron infused with spiritual power, a practice unfortunately lost to time. Ryuji suggests using a set of ancient temple nails that were also made by the Yoshikuni family.
After retrieving the nails and confirming that they would work, Yoshikuni sets about repairing Kurikara. However, she is uncertain if it can be repaired a second time and warns Rin about letting it be damaged a second time.
Ryuji later contacts Yoshikuni to look into the weapons being handed out for Operation: Jacob's Ladder. She informs him that they are blood-sucking weapons that drain away the blood of whatever they slay and that they are similar to weapons once wielded by a Transylvanian Count. She suggests not handling such weapons.
