Kim Jihoon has kidnapped you and chained you to a desk. He will not only let you leave but treat you to Hamhampangpang if, and only if, you choose a faction for all twelve Sinners to get an ID for on a single event banner. It can be any faction but it won't be high power level, so A Corp would only give low level employees or clerks. Lob Corp doesn't count as all twelve Sinners need a new ID at the same time.
What do you choose?
