First Half Stage 15 Strategy Tips
Tips for the First Half
- Use Slash, Shot, and Ice Characters
- Target the Phaneroplasmodium First
- Be mindful of SP management in Wave 2.
Use Slash, Shot, and Ice Characters
In the first half of Stage 15, the enemies have Slash, Shot, and Ice Plates, so you’ll want to build your team around that. Wave 1 has a mix of 3 small and medium-sized enemies, and Wave 2 has 1 medium-sized enemy, so bringing characters with multi-target attacks will help you clear waves efficiently and trigger Core Exposed states faster.
Target the Phaneroplasmodium First
The Phaneroplasmodium Yoju: Type 1225 that appears on the left side in Wave 1 has an SP-stealing skill, so watch out. Because of this, your top priority should be to put it into a Core Exposed state and take it down first.
Be Mindful of SP Management in Wave 2
A medium-sized Phaneroplasmodium Honju: Type 1225 appears in Wave 2. It has higher Plates and HP than the smaller version in Wave 1 and is particularly annoying because it also steals SP. Your stolen SP will be returned once you put it into a Core Exposed state or defeat it, so manage your SP carefully and focus on exposing its Core as quickly as possible.
Second Half Stage 15 Strategy Tips
Tips for the Second Half
- Use Slash, Ice, Wind & Physical Characters
- Beware of Attack and Plate Nullification
- Beware of Blast and AoE Attacks
Use Slash, Ice, Wind & Physical Characters
In the second half of Stage 15, the boss “Dimensional Identified Kaiju A: Divided Entity” has Slash, Ice, Wind, and Physical Plates. Since the boss has many different Plate types, build a team with corresponding characters to break them efficiently. Hikari Shinomiya is an excellent choice, as she can break two of the boss’s Plates and benefits greatly from the stage effects.
| Tips! | The boss’s Form Change buff stacks up to 3 times, altering its attack patterns based on the number of stacks. All stacks are removed when its Core is Exposed. |
Beware of Attack and Plate Nullification
The boss uses the skill “Charging Stance,” which nullifies one attack and temporarily makes its Resistances unbreakable. As shown in the image, when the boss’s Plates are crossed out, remove the attack nullification first using a Normal Attack or similar action.
Beware of Blast and AoE Attacks
The boss frequently uses Blast and AoE Attacks, so managing incoming damage is crucial. If your team struggles with survivability, consider bringing Defenders who can protect allies, such as Isao Shinomiya (5-Star) or Akari Minase (4-star).
Flurry of the Frontline Strategy Tips
Take Advantage of Stage Effects
| Stage Effects | - Each time the unit attacks a Kaiju, the unit's Slash DMG Dealt +5%. Max 10 stack(s). -Each time the unit attacks a Kaiju, the unit's Ice, Wind DMG Dealt +15%.

In Flurry of the Frontline, stage effects are active. This time, the stage effects synergize especially well with Gen Narumi (Japan's Strongest Santa) and Hikari Shinomiya, making it highly recommended to include Gen (Japan's Strongest Santa) and Hikari in your Squad for this mission.

Break Plates Efficiently
In the “Flurry of the Frontline” Fierce Battle Area 15, enemy Plates are Slash, Shot, and Ice in the first half, and Slash, Ice, Wind, and Physical in the second half. Break each Plate efficiently to gain an advantage by triggering the Core Exposed state.
Level Characters to 100
During battle, having a lower level than the enemy causes you to take increased damage, making it harder to meet the objective “Win with 0 incapacitated units.” Enemies in Stage 15 are level 100 and have high HP, so leveling your characters to Lv. 100 is strongly recommended before challenging the stage.
