When I took on an entire team in Team Swat Solo because everyone quit on my side and went 48 and 6, and lost due to the Time Limit. 4v1
Normally I would just highlight the highest pp play, but Kyoumei no true force was really the map the cost me the most to do. I kept retrying this map for hours until the day after I full combo'ed it first try :D I jumped out of my chair in happiness as it was my first 5 star+ full combo (5.14).
