Succubus in Wonderland Guide

This is a guide on how to progress through Succubus in Wonderland and obtain its various endings, as well as on how to complete side content. It is based on the officially endorsed guides for the game.

Main story
The name chosen at the beginning of the game can affect the ending : choosing the name "アリス" ("Alice" in Japanese) is one of the conditions for the genocide route.

After a series of cutscenes, the player will arrive in Castle Gate and be thrust into a tutorial battle where Lewis explains how the battle system works. Win this battle, then head south, where Lewis will explain how Cheshire Crystals work. Head west and then north to reach Mel Village. Alternatively, going south will bring the player to the Succubus House, but it isn't possible to go anywhere else from here (at this point in the game).
 * While traveling, try to interact with as many things as possible (examining objects, picking up treasures, talking to NPCs) to gain experience.
 * Also, try to collect as many of the Dinah Medals as possible. Their locations are described at the end of this guide.

Mel Village has the Empty House, a house with a Cheshire Crystal, books with gameplay information, a bed that can sometimes be examined for H-scenes, and where the player can listen to their current companion talk. It has the first of Hatter's shops, where the player can buy and sell various items, donate money to increase Hatter's selection of items, and erase their memories of defeat and reset their virginity. The strange house in the west is home to Lilith, who will be available as a bonus boss later in the game. It also has the first two touch challenges, which allow the player to recruit new companions.

Head north to Mel Forest. A dead end along the west side leads to a Hidden Room with treasure chests and the High Succubus touch challenge (though the latter probably won't be available at this point). Continue north to Stray Coast. If the player enters the cave that leads to Stray Coast, then turns back immediately, they will see a minor event with a mysterious masked succubus.
 * Most locations have a Hidden Room, and these often have touch challenges. Be on the lookout for their entrances.

The second area of Stray Coast has the first of the Lorinas: birds that play a strange song if given a certain code (mentioned by a nearby NPC) and describe the life of an unknown person if given a different code. The second type of code for this Lorina is 0006; make sure to give the Lorina this code as it's important later on. Stray Coast also has two more touch challenges. Finally, when the player goes through the north exit, they will see another event involving the masked succubus.

The first area of Edible Forest has a Nekomata who wants a Muni Eel; this is the first step in the Nekomata sidequest, in which giving the Nekomata specific fishes causes her to reward the player with new recipes, and completing the sidequest is necessary to unlock her touch challenge. The third area has an open window leading to an unnamed hut with a drink that shrinks the player; while shrunken, the player will instantly lose if they contact any of the Lesser Imps on the beach outside the hut (the Pooka, on the other hand, can be fought normally). Avoid the Lesser Imps and reach the end of the beach to meet Alice. The player will return to their normal size upon leaving the beach. Finally, entering the fourth area of Edible Forest will unlock Lilith as a boss (back in Mel Village), but she is very strong for this point in the game. The fourth area has the Downer Succubus touch challenge.

North of Edible Forest is Atuchu Cave. Its first area has an ambush where Reto and Lewis will be separated, and the former will be attacked by the mysterious masked succubus. This succubus, actually Lewis' sister Carroll, will bring Reto to 0 Vigor once, but will hold back after that, allowing her to be defeated. After defeating Carroll, there are a few cutscenes and the player will end up back in Mel Village. Return to Atuchu Cave and progress through the area. The second step of the Nekomata sidequest is in Atuchu Cave 3, and requires a Muni Tuna. Also in this area is a ladder leading to Atuchu Cave: Resting Place, where Alice can be encountered again. Atuchu Cave 5 and 6 have stronger enemies than the other areas, and the latter has a ladder leading down to Cave Village. There are three touch challenges in Atuchu Cave.
 * Examining the bed in Mel Village will lead to a H-scene with Lewis, giving her the Royal Aura skill.

Next are Nostos Village Road 1 and 2, the latter containing the second Lorina (give it the code 0009) and March Hare's house. Go inside and defeat March Hare, the leave and continue west to Nostos Village. There are actually two touch challenges in March Hare's house, but neither will be accessible at this point.

Nostos Village has a range of features including a chicken-counting minigame, a casino (which requires the prize from the chicken-counting minigame to enter), two touch challenges, and the secret boss Lina and Gina. To access Lina and Gina, give the code 6928 to a succubus in the area immediately west of the village, then find the portal in the south of the village and enter.

To the west is Zendegee Forest. This is quite large and complex, so consult that page for details. To progress, head west to Zendegee Forest: West and then turn north. At the end of the forest is a second battle with Carroll, defeat her.

Dinah Medal locations
There are Dinah Medals, and acquiring 40 of them is necessary to fight and recruit Alice.
