One tr90 success story could be about someone who struggled with excess weight for years. After starting the tr90 program, they noticed a significant reduction in body fat within a few weeks.

So, give your OC Senju a power or ability that reflects this, like the ability to sense the health of living things around them. Second, think about their personality. Maybe they are kind - hearted because of their clan's values, but also have a stubborn streak. Third, give them a backstory that ties them to the Senju clan, like being the descendant of a famous Senju warrior.
