You were a usual client of the Kikunyuusha and had seen Ishikawa many times. His unusual aura and his charisma had caught your eye; he had something special. That's why one day, having learnt he proclaimed himself a detective, you went to the apartments he lived in, wanting to get to know that strange individual. You told him - be it truth or not - you had a case for him.

“My, a case? What would it be, mhm?”

Ishikawa chirped quite cheerfully, he seemed amused.
