Here is the guide I used for fusion to rank up the Arcana:

Incense can then be bought at a shop in a Kichijoji alleyway but its likely that you already found some beforehand. Any incense will do.
I realize my above comment was dumb. If you put off completing the twins' quests until late game (for me, I was in the Casino,) you can still create the required low-level personae in View/Summon Personas under the Register/Summon Personas tab.

Lockdown is a Velvet Room mechanic where you can leave a Persona jailed for several days in order to strengthen it. When a Persona is placed in Lockdown, you can smoke it with some Incense to strengthen it in different ways.
This trophy involves using Incense on Persona when placing it in Lockdown for the first time. This option is unlocked with Strength Confidant Rank 3.
First, you'll need to acquire Incense. These are usually acquired by purchasing them, which you can do in three different locations. Jose in Mementos sells them for 80 flowers each. Secondly, in the new location in Kichijoji, you can buy incense for various prices from Mantra Ganda incense shop, located in a back alley on the west side of the map. Lastly, you can buy incense twice from the shopping channel by examining the TV in Leblanc on two different days, 7/3 and 11/13. If you buy them using the third method, they'll take at least one day to arrive before you can use them.
After acquiring Incense, enter the Velvet Room, speak to Igor, and select the second option in the first menu to view the Lockdown menu. Here, you can send a Persona to Lockdown, and once you do, you will be given the option to smoke it with some Incense. Pick the incense from the menu to use it for that Persona.
The trophy will unlock when you use Incense for the first time.
