Astonishing Personal Best Update!

In the daily challenge mode 'Hero Invasion', I've smashed my previous personal best (53.21M) by a huge margin!!! 79.39M! I narrowly missed 80M, but it was more than enough damage score to set a new personal record. As expected, 'Nameless' is just too strong (I've been saying this forever). I feel like I could go even higher if I strengthen 'Nameless' or add more support members. As of now (around 3:00 PM JST), my rank is 33rd. It's terrifying how there are still players above me even with a score like this... I wonder how long I can maintain this position.
