Azure Giant wasn't so bad,actually.With high physical resistance,all level up points into HP and Guardian's damage reduction Rasetsu Fist becomes manageable (unless the boss decides to spam too often, of course). So basically all that is needed is a bit of luck, or just overleveling (I'm pretty sure I was actually few levels lower the recommended level). 9F Tenshi wasn't much of a problem, I mostly invested in DEF, Iron Mountain Charge for damage.As for the skills, I had ATK buff and HP recovery, so she didn't use Sword of Hisou, since I didn't have a total 100% of buffs. I've defeated 12F Tenshi on my first try. After finally beating the Magatama I decided to see how fast she will rip me to shreds, without even changing skills and equips.At first I wasn't able to damage her, but when she got a DEF debuff, she started using Violent Motherland dealing zero damage to me.And since she stopped using Sword of Rapture, I was able to buff my ATK, plus silence from Star Sword Apologetics helped really well, so I dealt like ~3k damage with it. Not much,but she wasn't able to hurt me, so it wasn't a problem.
