One Piece, Vol. 5: For Whom the Bell Tolls by Eiichiro Oda and Naoko Amemiya

Once upon a time, Usopp was just a local boy with a talent for tall tales. Everyone in his little seaside village knew him as the joker who claimed to be a pirate captain and woke people up in the mornings by shouting "Pirates are coming!" But then real pirates landed on the beach…

Now Usopp's village is under attack by the Black Cat Pirates, one of the most legendary and feared crews on the high seas. And three young would-be pirates have joined him in defending the village: Nami the thief, Zolo the swordsman, and Luffy, the straw-hatted wannabe pirate with incredible rubber powers. Usopp is about to find out how an imaginary pirate stands up to the real thing… and what it means to be a real pirate. His neighbors would never believe it in a million years...

Usopp continues to be a hero. Lying bloody and the ground, the risk of death near and only caring about the kids and Kaya escaping. This leads to a great moment when Zoro and Usopp are running after Django, and Zoro throws his sword to cut down a branch that's blocking Usopp's sniper shot that defeats Django. So great.
Assistant Chef Sanji is introduced. Actually I'm always surprised how he's introduced. He just destroys Ironfist emotionally and bloody for disrespecting food and hits on his girl. So like, the majority of his personality. He then feeds pirate Gin from Krieg's crew and Luffy decides to make Sanji his cook.

Enemies defeated: Zoro defeats the Meowban brother Butchie. Usopp defeats Django!! Luffy defeats Klahadore (or “butler” as Luffy calls him). Sanji defeats Lt. Ironfist Fullbody Minister of the Navy.

Friends made: Going Merry! Zolo's old team Yosaku and Johnny the bounty-hunters. And by Luffy standards Sanji, and Chef Zeff.

There always has to be a balance in the story when the titular character is on the verge of omnipotence, and in this issue, between the conclusion of Captain Kuro's arc and the beginning of the cook's quest, the manga demonstrates all its versatility, knowing how to give the right amount of space without overdoing it.
