Rin vs Kotomine

Nasu-san CHECK!
Ah. Rin has the better specs, but 80% of the time, Kotomine would win. It's not easy for humans to conquer trauma printed into them and what this fraud of a priest excels at is opening up the trauma of the enemy.
Since Rin has the goof-up girl trait, she has a lot of traumatic experiences, and having these poked at would make her unable to take advantage of her true potential.... Of course, even if they didn't know each other, Rin would still have a hard time. The executor side of Kotomine, a combat expert with over 10 years of experiences in killing magi, would be the counter of Rin's talents.
