Throughout the game, Lionel appears to be Mina’s greatest ally and benefactor. He guides her investigation into the failing Spark Generators and positions himself as the island’s protector. However, as the story progresses, clues begin to suggest that far more is happening beneath the surface. The final chapter reveals that Lionel has become deeply connected to the dark forces affecting Tenebrous Isle and ultimately stands as the final obstacle between Mina and the truth.

This revelation recontextualizes many earlier story moments. Conversations that once seemed supportive take on a more suspicious tone, and the mystery surrounding the generators and the island’s ancient power finally receives an answer.

Location of the final battle

The final confrontation occurs within Radiant Manor, the last major dungeon in the game. This sprawling location serves as the culmination of everything players have learned throughout their adventure. The manor contains powerful enemies, difficult navigation challenges, and several boss encounters before the final showdown. By the time you reach Lionel, the game expects you to have mastered hollowing, sidearms, positioning, and resource management.

How to defeat the final boss in Mina the Hollower

Step 1

Enter the arena fully prepared with healing items and your preferred sidearm setup. The fight is significantly more demanding than most previous encounters, making preparation extremely important.

Step 2

Learn Lionel’s attack patterns during the opening phase. Many of his attacks punish aggressive play, so focus on observing movement cues before committing to damage opportunities.

Step 3

Use Hollowing strategically rather than offensively. The invulnerability frames provided by burrowing underground are often the safest way to avoid large attacks.

During later phases, the arena becomes more chaotic and projectile pressure increases. Prioritize survival and positioning over maximizing damage output.

What happens in the ending

After Lionel’s defeat, the corruption consuming Tenebrous Isle is finally brought under control as you complete the Prime Generator objective. The island survives the crisis, but the ending is far from a simple victory celebration. Mina’s actions throughout the adventure come with consequences, and the conclusion carries a bittersweet tone rather than a completely happy resolution.

The ending focuses heavily on accountability and the dangers of relying on powerful forces that are not fully understood. Throughout the game, Spark technology brings prosperity to the island, but the final revelations show the cost of that dependence. The narrative uses Mina’s success and failures to reinforce this central theme.

How the ending connects to the rest of the story

From the opening shipwreck to the final battle in Radiant Manor, Mina the Hollower constantly builds tension around the mystery of Tenebrous Isle. The generators, the monsters, the rebellion, and Lionel’s leadership all appear disconnected at first. The ending brings these elements together and explains how each piece contributed to the island’s downfall.

The final moments also leave enough unanswered questions to keep players discussing the story long after the credits roll. Rather than providing a perfect resolution for every character, the game chooses a more nuanced conclusion that fits its gothic atmosphere.

Is there a true ending?

Players pursuing complete completion can discover additional secrets, optional bosses, and post-game content throughout Tenebrous Isle. The community commonly refers to a “true ending” or “100% ending,” which requires extensive completion beyond simply defeating the final boss. This includes optional objectives and hidden content that expand on the game’s lore.


Mina the Hollower closes its story with a demanding battle against Lionel and a conclusion that balances victory with sacrifice. Radiant Manor serves as a fitting final dungeon, while the ending provides meaningful answers without removing all mystery from the world. Whether you’re interested in the story, the boss fight, or pursuing the 100% ending, the finale delivers a satisfying conclusion to Mina’s adventure across Tenebrous Isle.
