A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing.

Can I choose Hida Ishi to bow for Yogo Asami's ability, and then have the bowing negated by Ishi's trait?
Hida Ishi: Crab Clan • Berserker Ishi has +2F/+2C while opposing an army with more units than his army. Negate Ishi's bowing from other players' cards' effects.
Yogo Asami: Scorpion Clan • Distracter Battle/Open: Any number of times per turn, bow Asami and target a player: He must target and bow one of his unbowed Personalities.
