Hello!

Unfortunately, Iruka Fragment is currently not in the Treasure of Sage event. The only way for you to get his fragment is through Fragment Refining. If you wish to have Iruka back in Treasure of Sage, you can suggest it through giving feedback or answering the Event Feedback forms that are usually posted at our News Section. If you want, I will note it too for my report as a Suggestion for the next Treasure of Sage event. Thank you.
