| 7 | After beating the Guardian Boss, you will unlock another door that lets you travel back and forth to the Desert of Doors and B14 of Caina. Use this chance to recoup and prep for the final stretch. |
| 8 | From B14, head down and you need to go down another set of randomly generated dungeons, so make your way down up to B20. |
| 9 | At B20, you will see another giant door, head towards it to open it and you get a glimpse of Akihiko's being recruited by Mitsuru to join SEES. Again, the group decides to regroup for now. |

| Monad Bosses | |
| Chaos Cyclops | Eternal Eagle |
| Nemean Beast | |
Click the names above to skip to a certain boss.
Metis and Akihiko are useful for this fight since Metis can target the Natural Dancer's Ice Weakness while all of Akihiko's Attacks all deal neutral damage into the Harem Dancer. They're also both Strike-type attackers, which isn't resisted by either enemy.

Even though Yukari specializes in Wind, you'll want to bring Ken instead as your main support to avoid Yukari getting beat down by the Harmony Giant's Electric attacks. If you need an extra Wind attacker, you can always bring Metis with Garula as one of your other party members.
Harmony Giant and Judgement Sword Boss Guide
Chaos Cyclops is one of the Monad Bosses found inside Caina. This boss is relatively easy as long as you don't bring anyone weak to Fire and Ice attacks and you remove his Defense buffs.

Eternal Eagle is another Monad Boss found inside Caina. It will be accompanied by two Jealous Cupids that like to Charm your allies, so make sure to deal with them first.

Nemean Beast is the final Monad Boss you can encounter in Caina. It will fight alonside an Enslaved Beast, but you can easily take both of them down using AoE Fire and Wind Skills.

| Rank | Character | Explanation |
|---|---|---|
| 1 |
 Ken
|
On top the usual Kouga, Arrow Rain, and Mahamaon, Ken will gain access to Mediarama making him an amazing all-rounder. His characteristic on top of the limited resources is still amazing for quickly building up his Theurgy Gauge. |
| 2 |
 Mitsuru
|
May seem lackluster at first but will be amazing once you get her Characteristic at B8 which increases party's chance to Crit when under any Status Conditions. |
| 3 |
 Yukari
|
Still the mainstay main healer but Ken does overshadow her since he also has Pierce attacks. Almost a necessity for the second Guardian Boss if not for Metis. |
| 4 |
 Metis
|
Best character to handle the bosses in Caina but doesn't perform that well against the regular enemies. |
| 5 |
 Akihiko
|
Raises in useability thanks to finally getting access to Ma-Kaja skills on Aigis and getting his first characteristing back in Cocytus. Not useful against the last boss but fares pretty well agaiinst the Regular Enemies. |
| 6 |
 Junpei
|
A bit lower than Koromaru initially but is an amazing choice once you get Mitsuru's Characteristic which increases party's Critical chance when attacking enemies under status. |
| 7 |
 Koromaru
|
Falls off quite a bit since a lot of the enemies here resist Fire or Dark but still a decent choice against the Harmony Giant and Judgment Sword. |
After beating the bosses in B9, you will have access to locked chests that need one Twilight Fragment. Two of these contain the items for Mitsuru's, Yukari's, Koromaru's, and Ken's Linked Episodes, so make sure to allot 4 Twilight Fragments for these.
How to Farm Twilight Fragments and All Locations
After finishing Caina, you can unlock new Theurgies with Metis' Charging Blitz and upgrade Fuuka's Oracle to Revelation.
Metis' is just the same as Aigis' Maximum Firepower but deals Strike damage instead meanwhile Fuuka's being great in a pinch like fully restoring HP and SP.
