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 activate Daigotsu Arakan's ability, interrupt it with the Courage action to discard Ichigo's Guard, and then equip that Ichigo's guard from the discard pile with Arakan's ability?
If not, could I use courage to interrupt some other action (one that does not create a Fear effect), just to get Ichigo's Guard into the discard pile so that on a later action I could equip it with Arakan's ability?

You need to target the attachment prior to the Interrupt window on Arakan's action, so the Ichigo's Guard would need to be in discard already. However, discarding it to Courage any other action earlier in the turn is perfectly acceptable.
