IMO, you should try to smith him. Grinding the 100th floor will also consume lots of resources thanks to those R5 yaris, so you'll have to repair your swords a lot.

If you want the extra koban you should try to smith him first in the first few days of the event and if you get him you bring him to the UTC map (you'll probably be able to bring him till 50th floor if you level him up a little), otherwise just do the event and keep trying to smith him. It took me about 4 days to smith him.
