Now its time for the bikini team! (+ Akihiko)
Ok lets make this clear before we move on, if you want to make this fights easier, use real armor xD, you should have way better gear at this point, the maid outfits for example, those give a good bonus xD
Judgement sword
Don't use any zio spells on it, they have no weakness, you should just try to get crits on them. I used Yukari because the bikini team requires her, but you shouldn't bring her if you want this to be easier, just use ken instead if you need the healing
Tentarafoo works on them sometimes, but as you can see on the video, its not very reliable
Stasis Giant
Pretty much the same as Judgement sword, but they resist fire and null slash, they are affected by charm but like the other, its not reliable
Note: on both fights, try to equip accessories with counter
Getting to these bosses was harder than fighting them... sp recovery prices are too high! 250k when i am at half with 4 characters! i am not even worried about fighting dangerous enemies anymore, i am more worried about needing more than 1 skill to kill them xD
