、。
Even if I fail, I'll give it another shot.
Literal
By-chance fail-even-[concessive-ても], once-more work-hard-[polite-ます].
頑張る ('to do one's best, to persevere') is the quintessential Japanese word for effort and endurance. More culturally loaded than 'try' — it implies commitment to persist against adversity, and is used in everyday encouragement as much as competitive settings.
