So we can't get title Saint Savior (+9 mdef)? I was working on this too
You can. Quest you're mentioning is totally unrelated.
[Saint Savior](+9 mdef) (Expires after 60 days) Collect 20 Mulberry Hearts from new daily from 'Secret Man' 546 628 (Daily quest can be unlocked from completing 'Pestle of Re. Access'; Right after charging the crystal in SOT/Aba, you may turn in the heart to get exp+Stealth pot instead. Trash the quest rewards and keep collecting the hearts to achieve this title)
