The End of Alter Egoism F95 Complete Endings Guide
1. Game Overview
The End of Alter Egoism (Japanese title: 終末のオルターエゴイズム) is an adult RPG and visual novel hybrid developed by ONEONE1, the studio behind acclaimed titles such as Samurai Vandalism, Oni & Blade, and Ideology in Friction. The current release is version 1.02.
The game’s tagline — “A story of a buddy duo who, by filling each other’s flaws, weave a bond together — not alone, but as two” — perfectly captures its dual-protagonist structure. Two girls with opposing strengths are thrust together inside the prestigious Iris Academy in Hinomoto, and the player steers both of them simultaneously through a branching story of revenge, redemption, and self-discovery.

3. Core Mechanics Explained
Dual-Protagonist Switching
At almost any point in the game, players can instantly swap between Shirayuki and Yozuru with a button press. This is ONEONE1’s most refined implementation of this mechanic to date — both heroines stay together throughout the adventure, and you leverage their complementary skill sets to navigate combat and story events.
Combat System
The combat draws influence from Samurai Vandalism while returning to the broader gameplay loop of Ideology in Friction and Oni & Blade. Key elements include:
| Feature | Shirayuki | Yozuru |
| Combat Style | Physical / Tactical strikes | Magical area attacks |
| Best Against | Lightly armored, fast enemies | Multiple enemies, boss targets |
| Weakness | Magic-heavy opponents | Close-quarters fighters |
| Solo Battle? | Yes — certain battles are solo | Yes — certain battles are solo |
Virginity & H-Status Flags
Before taking control of each heroine for the first time, the game prompts you to set their initial experience level. This choice triggers a unique H-scene at the start and sets various flags that influence how NPCs interact with the characters, which side events become available, and what options appear in battle defeats.
Promotion Exams
Iris Academy uses a Promotion Exam system with five escalating stages. Each exam unlocks new areas and story content, but also introduces new H-scene opportunities tied to patrol encounters, night missions, and NPC interactions. Completing all five exams is required to access the game’s later story routes.
4. All Routes & Story Paths
Common Route
The Common Route covers the first half of the game, regardless of which character-specific path you’re steering toward. Both Shirayuki and Yozuru are enrolled together, take promotion exams, explore Iris Academy, and interact with the broader cast. Your choices during this phase — especially your combat victories and defeats — begin tilting the story toward one of the later branching routes.
Dahlia Route
Unlocked through specific story progression, the Dahlia Route centers on confronting Dahlia, one of the game’s primary antagonists. Key locations include:
- Dahlia’s Hideout — Investigate and infiltrate
- Kamiyado — Intermediate story hub
- B3F Dungeon — Obtain the Rusty Sword and Broken Mirror
- Underground Fighting Arena — Multiple battle encounters with route-splitting outcomes
- Tōto Ancient Ruins — Search for Miran side quest
| Event | Trigger Condition | Outcome |
| Underground Arena 1 | Reach Dahlia’s Hideout | Side episodes unlocked |
| Jun Kamata Battle | Solo battle (either heroine) | Victory = story continues; Defeat = H-scene triggers |
| Legacy Quest 2 | Find Rusty Sword + Broken Mirror on B3F | Unlocks Legacy Quest 3 |
| Search for Miran | Talk to guard at Tōto Ruins | Side episode: “Searching for the Missing Friend” |
Academy Route (Iris Academy Main Story)
The Academy Route tracks the girls’ Promotion Exam progression through five stages, each at different locations on and around the academy grounds. This is the backbone of the main narrative and must be completed regardless of which ending you’re targeting.
| Exam Stage | Location | Notable Events |
| Exam 1 | Iris Academy Campus | Initial enrollment challenges |
| Exam 2 | Mt. Tsukuba – 1st & 2nd Station | Night exposure events available |
| Exam 3 | Mt. Tsukuba – 3rd Station | Fishing challenge (catch Tsukuba Iwana) |
| Exam 4 | Mt. Tsukuba – 4th Station | Night campus selfie side H-events |
| Exam 5 | Iris Academy – 1F (Night) | Orgy or combat depending on H-status |
5. All Endings Guide
⚠️ MAJOR SPOILERS BELOW — All endings and how to unlock them are covered here.
The End of Alter Egoism features multiple endings tied to a combination of your combat record, story choices, and the H-development status of each heroine. Unlike some visual novels, there is no single “wrong” ending — each outcome reflects the path you chose.
★ True / Best Ending
Bond Completed — “Not Alone, But As Two”
Both heroines resolve their personal conflicts. Shirayuki uncovers the truth about her mother’s killer; Yozuru masters her magic and finds forgiveness. Their bond as a true buddy pair is cemented. Requires completing the full story route with key victories and relationship milestones.
✓ Good Ending
Shirayuki Route End
Shirayuki achieves her revenge goal. Yozuru’s arc remains partially unresolved. Unlocked by prioritizing Shirayuki in solo battles and key story decisions. A satisfying but incomplete conclusion.
✓ Good Ending
Yozuru Route End
Yozuru fully controls her power and secures her future as an agent. Shirayuki’s revenge is put on hold. Reached by focusing on Yozuru’s development and battle victories throughout.
✗ Bad Ending
Academy Failure
Both heroines fail their promotion exams due to too many exposures or defeats without recovery. The bond breaks and both are expelled. Triggered by consistently losing in patrol-related encounters.
✗ Bad Ending
Corruption Route
One or both heroines become too enmeshed in the underground arena lifestyle. Their original goals are abandoned. This ending is triggered if the “Slut” H-title is acquired on both heroines before Exam 5 and certain story flags are not resolved.
How to Unlock the True Ending — Step-by-Step
- Complete all five Promotion Exams without letting both heroines fail simultaneously.
- Win the Jun Kamata battle with at least one heroine. A loss by both triggers a bad flag.
- Complete the Legacy Quest chain: obtain the Rusty Sword and Broken Mirror on B3F.
- Complete the “Search for Miran” side quest at Tōto Ancient Ruins before the Dahlia confrontation.
- In the Dahlia Route climax, use both heroines in coordination (switch during battle) rather than relying on just one.
- Do not let either heroine hold the “Slut” H-title before Exam 5 if aiming for the True End — this triggers the Corruption flag.
- After the Dahlia confrontation, choose the dialogue option that emphasizes partnership over individual revenge.
- Complete Shirayuki’s revenge subplot and Yozuru’s control subplot within the same playthrough. Both must be resolved for the True Ending to trigger
6. H-Development System
The End of Alter Egoism tracks sexual development across seven categories for each heroine. Development is permanent within a save file and influences dialogue, side events, NPC behavior, and which ending flags are active.
| Category | Effect When Leveled | Affects Endings? |
| Oral | New service interactions with NPCs | Indirect |
| Breast | Unlocks chest-based side H-scenes | Indirect |
| Pussy (Virginity) | Flags heroine as non-virgin; alters defeat scenes | Yes |
| Anal | Unlocks Exam 4 and Exam 5 specific scenes | Yes |
| Service | Affects NPC encounter options | Indirect |
| Exhibition | Night campus exposure events activated | Indirect |
| General Lewdness | Triggers “Slut” H-title at high levels | Yes — Ending Flag |
H-Scene Categories at a Glance
| Scene Type | Description |
| Main H-Scenes | Core story-integrated scenes, including arena defeats and story beats |
| Side H-Scenes (SEH) | Optional side content unlocked through exploration and NPC events |
| Sub H-Scenes | Repeatable scenes tied to specific locations or heroine stats |
| Loss Battle Scenes | Triggered by losing mandatory battles; vary by virginity/anal status |
| Virgin Start Scene | Special unique scene available only if initial status is set to virgin |
7. Tips for Every Playthrough
| Tip | Details | Priority |
| Save before solo battles | Outcomes change based on virginity/H-title status | High |
| Complete side quests early | Some side episodes vanish if main quest advances too far | High |
| Switch heroines in boss battles | Exploits enemy weaknesses — purely physical bosses fear Yozuru’s magic | Medium |
| Set initial experience deliberately | Virgin start = unique early scene; non-virgin = altered interactions | Medium |
| Don’t upgrade General Lewdness hastily | Slut title on both girls is an ending flag | High |
| Talk to Abiko inside Dahlia’s Hideout | Triggers the “Senior Wandering Naked After Bath” side episode | Low |
| Fish at Tsukuba during Exam 3 | Catching the Tsukuba Iwana is a required objective — don’t skip the fishing point | High |
| Second playthrough for content | Play as non-virgin on second run to access different initial scenes | Medium |

Can you finish the game as a virgin?
Yes. The H-development system is entirely player-driven. Both Shirayuki and Yozuru can remain virgins for the entirety of the game, including reaching the True Ending. H-scenes are optional content triggered by player choices and battle losses you can avoid.
