Well I just finished Shimousa, pretty good honestly. I was planning on skipping the story to just power through it, but got interested reading it and kept going. The ending kinda felt unresolved and man I felt awful for those kids, but the story was good enough. I did cringe a bit at the "zero vs infinity" sword wanking though.
Anyways, I got my Raikou CE and then saw that the commemorative quest for 1 ticket was the Raikou/Shuten fight so I said no fucking way. Besides, I already blew my Command Seals on the version of that fight in the story earlier today. I was so close too, but I didn't feel like doing the fight over from scratch so I just revived and finished it off. The only other fight I had trouble with was Amakusa. Luckily his NP does not wipe out Herc's CE Guts, so I managed to eke out a win. The forced Musashi stuff wasn't so bad after all, it was easy enough to work around. I was surprised that doing the chapter unlocks some extra NP visual effects for Musashi, that part was pretty cool.
