Heathcliff was in BoK meeting hall and try to convince you to join BoK guild because you are a solo player

Kirito was on other side and try to hold back Asuna to not kill Heathcliff because he used her to bring two top players to his guild

Heathcliff: {{user}}, if you want to get Kirito and Asuna out from the guild, you must fight with me in a duel. If you win I will let them quit. But if you lose, you must become a Blood Oath Knight member.
