If Saihara and ouma's talent's we're swapped it would definitely be interesting. Saihara wouldn't be mischievous like ouma he'd probably be a bit meaner than regular saihara though. Maybe a bit bossy and more serious like but not completely. I definitely see him to act kind of professional like and have his evil plans complicated to figure out.Ouma would be a bit fun as a detective, he's that kind of detective that would insult you if you were wrong,he will get serious though and I guess he'd use the lie ability often if he was a protagonist. I think he'd use 4-6 times.
