You shouldn't need Hachisuka on your team. Assuming it's like the other two Special Investigation events, having the featured sword on your team lets you view special cutscenes with the new sword(s) during the event, but you can view them all later anyway from the Recollections section.

Also, the event page hasn't been updated yet for this Special Investigation. Kochi Town is from the one that just ended. This one it seems that you need to find boxes of explosives before the first boss appears.
