Tales of Berseria

You will earn this trophy for clearing a side quest related to Rokurou. This is a long side quest involving multiple fights. You do not need to do the individual parts immediately as you cannot complete the whole side quest until after you have unlocked the Last Dungeon, so you can start it all in one go then, but that is up to you.

During the main story events in Loegres and Danann Highway, there will be a skit about a powerful discovery pointing at a daemon. This daemon is Orc Kong. In the section between Port Zekson and Loegress, after leaving Port Zekson, take the eastern transit to the next field part and you will find it. Defeat the daemon.

In the harbour part of Reneed, there is a group of three NPCs between the docks and the wooden bridge towards the town. They will not be there when you arrive at this town the first time story-related, so do not bother searching them then. After you have unlocked the geoboard, you can continue with this side quest. Approach these three NPCs and they will talk about a monster in East Laban Tunnel. In this dungeon, defeat the daemon Serket that is at the end of the dungeon. While you are here, do not forget to unlock the geoboard for this area and also get the Katz Chest.

In Port Cadnix, talk to the two sitting NPCs in the inn. This part is available after arriving in Taliesin. Go to Votigern and then to the upper platform on the east side. Defeat the daemon Lancelot.

After unlocking the Last Dungeon, go to Loegres and talk to Tabatha in the inn. Head to The Empyrean's Throne and defeat the daemon Dragonfolk which is located on the upper platform at the east side. Afterwards, head back to the inn in Loegres and watch the scene. You will get Rokurou's Colour Variation outfit and the trophy will unlock.
