Sakurada was the maiden name of Adachi's wife
Near the end of Hero Bank 2, Adachi reveals that he created Sekito as his agent to stop Yagami because no one would help him due to his crimes in the original game. Later on, Sekito's message adds that the boy was created in the image of Adachi's dead son.So why did Adachi specifically choose Sakurada among many options as Sekito's surname? It only makes sense if it was the maiden name of Adachi's wife.
