Making a Sparkling Rock

I met Sophia in map. She's working on her dream of becoming an alchemist. To make the sparkling rock, she says she needs 30 Squishy Liquids, 30 Leafs, 30 Octopus Legs and 1 Arcon's Blood. Everything looks reasonable enough... wait, Arcon's Blood?! Fortunately, Sophia knows where to get some. She says to have a chat with Manji, who's somewhere around map.

Sophia told me that Manji has some Arcon's Blood, a key ingredient to make a Sparkling Rock.
