If you have the unit himself, you can just feed him the manual through Power Up. It will have a chance to power up his special (-1 turn cd). For rare manuals like this, you'd best wait for 2x chance events, but luckily one's going on right now.

Mind that it can only level up your special if it's the same special's manual.
