Tsunoda has a very upbeat and perky personality that tends to drive her co-workers crazy. She forever follows Ton around, praising him for his golfing skills. Retsuko brings this up to Tsunoda during dinner to which Tsunoda responds that she does this for a reason: to stay on the management's good side and that she is fully aware that her co-workers think less of her for it. Tsunoda has an active social media and dating life and tries to drag Retsuko and Fenneko into it.
