Hardest boss to 10-second rank in the BN series. Still easy.
Challenge I was given:
1. No using Light Soul MegaMan (basically means no Full Synchro)
2. Save the Mystery Data
3. Do it in 10 seconds (my personal requirement)
First, I did it my own, then accomplished the challenge twice -- Blue Moon and Red Sun, then there are 2 more bonus fights.
