After you've accepted the subquest, head towards the Tokyo Metropolitan Government Building and approach Samael to begin the battle.

Defeat Samael so that you could unlock his Special Fusion. If the option for his Special Fusion does not appear, it may be caused by the lack of demon components in your compendium.

Inherit Abyssal Mask
Samael will unleash all sorts of attacks that deal status ailments to your party. It is recommended that you have your character inherit Abyssal Mask so that you'll reduce the chances of acquiring a status ailment.
Demons With Abyssal Mask
Remove Status Ailments Immediately
If you've acquired status ailments from Samael throughout your battle, his innate skill will enhance his attacks to a greater degree and cause you to lose much of your HP.
When struck with a status ailment, it is best to recover from it using Me Patra, Amrita Shower, or Amrita Soda so that you'll avoid being incapacitated in battle.

Prioritize Defeating Samael's Minions
| Demon Minions | Weakness | Resist | Null |
|---|---|---|---|
| Naamah |  |
|  |
| Eistheth |  |
| |
| Agrat |  |
|  |
| Lilith |  |
| |
During the first round and the time that follows after he casts Magatsuhi, Samael will summon Naamah, Eisheth, Agrat, and Lilith in that order.
If there are two or more of his minions in the field, then they will acquire buffs from each other that are supplemented by their innate skills. Prevent this by prioritizing the defeat of each minion summoned in battle.
