Sword Art Online: Alicization

Before the duel, Sortiliena warns Kirito that the secret of the Levinteinn family's power is imbuing their sword with the blood of their enemies, thus Volo's request for a match with real swords. During the duel, Kirito manages to increase the power of his sword and scratches Volo's shirt before the match is interrupted by one of the instructors and declared a draw. Later at night, Kirito discovers that the zephyr flowers he was growing were destroyed by two classmates with a grudge against him. As he laments, he is instructed by a voice to use healing arts to transfer life energy from the other flowers in the garden to restore them. The next day, having learned from Kirito's match, Sortiliena defeats Volo in combat and graduates as First Seat, and Kirito presents her with the zephyr flowers as a parting gift. Later, Kirito and Eugeo are promoted to Elite Swordsmen.
