Recently, a troublemaking crow has appeared on Third Street. After suffering from its tricks, Tama and the others are joined by Bull, who has also had a hard time because of it, and they decide to stand against it to teach it a lesson. After a fierce scuffle, Bull takes off after it, but what he finds at the end of the chase is...

Bull is the berserker of Third Street! But lately, it's been noticed that he isn't really a bully deep down. Tama and the others aren't afraid of him anymore. As Bull frets over things not going his way, he comes across a sneak thief's mask. Bull puts it on and appears before the others, declaring himself "Masked Bull." What will Tama and the others do?
If I'm no longer the berserker who 
quiets crying children with fear,
.لم أعد بول الذي يجعل الأطفال المتباكين يصمتون من الخوف
Die Kinder werden mich auch
nicht mehr fürchten und weinen.
Si ya no soy capaz de hacer
que un niño deje de llorar,
Je ne suis plus celui
qui arrête les larmes des enfants.
Se non sono più quello
che fa piangere i bambini dalla paura,
Se eu deixar de ser o arruaceiro que
cala de medo até crianças que choram,
Если я больше не Берсерк, при виде 
которого дети перестают плакать,
