Ichiru- Is the only person I can actually see him getting something for. Probably make dinner for the two of them and something practical, like...a scarf, hat, gloves And maybe return the trenchcoat he stole off your dead body and has been wearing for the past year
Everyone else he wouldn't get anything for...because not a single person is actually 'close' enough to deserve anything BUT...someone would probably cook a very large meal in the kitchen that was not fancy by any means, but a very hearty homecooked meal that was enough to feed almost everyone.
No one would know it was him unless they'd been in there themselves.
