How to Complete The Guardian of Light

Talk to Goko and Light Up 4 Pagodas

Objectives
1	Head to the southern portion of Taito and proceed towards Goko. Interact with him to begin The Guardian of Light Subquest.
2	Goko will instruct you to head towards the barely visible pagoda not far from your location. Head towards there, and examine it to light the pagoda.
3	Goko will further instruct you to light up 4 pagodas located in specific areas. Since you've lit up the first one, you will need to light the remaining 3 that are located in Shinjuku, Shinagawa, and Minato. Do note that you will need to light up the pagodas in order for them to materialize on the map.
4	Head towards the Government Building 2, located at the Shinjuku Region. From there, examine the second pagoda to light it up. Goko will now tell you the location of the third pagoda.
5	Proceed towards South Shinagawa, located at the Shinagawa Region. Follow the objective marker on the map, and light up the third pagoda so that Goko will tell you the location of the fourth one.
6	For the last one, head towards Tokyo Tower in the Minato Region. Once you've lit up the final pagoda, talk to Goko and face Marici in battle.
7	Once you've defeated Marici in battle, you will be able to claim 2x Battle Sutras from Goko and acquire her as a demon recruit in your inventory.

How to Beat Marici

It is recommended that you stack up resistances against Marici and use Dark or Almighty Skills against her in battle. Do not use Light Skills, as Marici will reflect them in combat.

Additionally, you should not bring demons that are weak to Ice and Light during this battle as Marici has access to said elemental attacks, which it can use to exploit your weaknesses during battle.

Bring Recovery Items or Skills to Prevent Mirage

Marici will be using Mirage against your party to make them ineffective against battle and reinforce her attacks to be more potent. It is recommended to use Patra, Me Patra, or Recovery Items that can rid the Mirage ailment.

Mirage Status Ailment Effect and Skills

Don't Use Pierce Attacks Against Marici

Do not use Pierce attacks against Marici, as her Might of Dawn Skill will counter it and retaliate with a heavy Light attack. This skill also induces the Mirage ailment, so it is recommended to use other Physical Skills in battle.
