Like a Dragon: Infinite Wealth - 21 - Substory 19: Home to Roost
This substory starts deep in the dangerous area of Aloha Beach, so navigate carefully until you reach a beach chair that calls to Ichiban, give in and have him rest on it to start.
As he wakes up hours later, he will feel quite heavy and it turns out a bird will have picked his hair as a nest after losing his mother! Ichiban will need food for himself and for the little Joseph, and thus you'll have to make your way to the ABC Store in less than two minutes with slightly clunky controls, be especially wary of Sumo wrestlers and cars when crossing the road, it's not too difficult.
Once you reach the store, cutscenes will ensue and lead to a fight with two level 9 Poachers, shouldn't be too difficult to deal with.
The substory ends after a few more cutscenes, your reward is the money you got from the fight and the ability to talk to Joseph at Revolve for items every now and then!
