Todu in Anime Vanguards (also known as Aoi Todo from Jujutsu Kaisen), is one of the new additions in the game’s first major update. He is a Mythic unit and can be obtained through Summons. However, if you already have him and want to evolve Todo into his Todu (Unleashed) version, you’ll need an item — a Broken Pendant. Here’s how to farm this item.

You can get a Broken Pendant by completing Shibuya Legend Stage 2. Since you need 12 of these Broken Pendants, along with Green, Blue, Yellow, Purple, and Rainbow Essence Stones and 15,000 Gold, you can farm the Shibuya Legend Stage 2, as you will get 1-3 after each completion.
You can get the Green Essence Stones through bundles, challenges, and Legend stages, but the other colors need to be crafted with Green Essence Stone and Gold. And to craft a Rainbow Essence Stone, you need 1 Blue Essence Stone, Purple Essence Stone, Yellow Essence Stone, Pink Essence Stone, Red Essence Stone, and 500 Gold. The crafting area is close to the Evolve area, so it's easy to reach if you have all the materials.
