Luba & Friends: Luba vs the Oni Queen, also known as Ao Oni Rising. is a oni game that revolves around Yao discovering a material she needs for a superweapon she aims to build for world domination (to turn everyone into onis). It does not revolve around horror but instead revolves more on adventuring what's more across the protagonists themselves.
To find out more about this project, head over to this wikia; 
Yao, the Queen of the Onis, has crossed between worldly gates to search for a power of energy she can harness to regenerate her onis and skyrocket her population. To do this, Yao decides to build a superweapon to start turning worlds to onis. One of her materials she needs is an raw crystal essence that hasn't been used by onis. To find one, her target destination is the Ao Oni Mansion that Hiroshi's gang went.
Goddess Zydona discovers this, and calls her four pupils: Luba, Jack, Niki, and Steve to solve the quest. Gods and goddesses do not have the power to banish otherworldly evils, so the four must go to the mansion and investigate while Zydona's shrine maidens Callie and Aubrey were busy on other missions. The four go in the mansion, but it all turns into two long days.
The team go out of their own ways when an Oni ambushes them and Luba went east. Luba is all alone, but as soon as she explores around she recovers person after person. Luba and Niki end up splitting up from Jack and Steve for a while when the Oni is on the chase for them in a room where the only safe route is a underground tunnel.
When the gang is reunited, Niki warns about a force that is trying to eat the soul out of people, which later marks Niki as an "ideal subject" for experimentation. The gang uses a extendable ladder to enter the secret room in the attic. However, a smoke bomb is thrown and Yao salvages the crystal and knocks the gang back down.
Luba hears that the Crystal had been stolen, and with no choice they have to get to the exit from the other side. Meanwhile, Callie and Aubrey had already finished with their mission and are on their way to the mansion.
Another smoke bomb is thrown at the gang and Niki was taken, and when they enter the annex a mysterious black wind comes in and swoops Jack and Steve away.
Luba, upon walking around sees Niki again run up the stairs. Calling for her and had gotten no response, she comes up to the stairs to the dining table room with the fireplace. Luba tries to talk to Niki, but she stands firm.
Niki then tells Luba that she wants to suck her blood. Pulling out a meat cleaver and with no means of escape, Luba prays to Zydona, and due to otherworlder circumstances Zydona can only block Niki's position. This however, buys Luba time to hide in the closet for around 1 hour. 1:00 A.M.
1:50 A.M: Callie and Aubrey find Luba in a closet. Callie states that they are here to help out the mission, and that the Niki that tried to kill Luba may be an imposter by the Onis. Callie and Aubrey then split up. Callie is going to setup a hideout in the mansion to plan a secret plan. Aubrey is going to go after Jack and Steve.
Luba finds a "fake" Taerin written by the Onis, and takes it. She says that Zydona is supposed to be faithful and pacifistic, while the fake one is very biased, the translations are broken and aren't faithful.
Aubrey, heading behind the Mansion by a window, finds Steve and Jack in a Jail. She finds a document regarding SpyOnis, and it says that to make a SpyOni they have to use one Oni and one human to make the clone. Then, the Oni takes control of the human analyzed.
Luba tries to use the garbage disposal she found in the annex to destroy the fake Taerin. The fake Taerin is rejected, and gets instead a pair of x-ray glasses and a stake.
The fake Niki comes after Luba, however Luba then pulls out the x-ray glasses and sees that Callie was right; the fake Niki was a SpyOni. Ramming her with the stake, she impaled the oni dead. The Oni drops a paper regarding a guardian to a secret Oni Lair called Aquarius. She saves the paper for later.
Callie saw that Luba killed the SpyOni, and invites her for a secret ritual; they'll pray to Zydona to bless a dagger that they'll use to kill one oni. After praying, Luba leaves the room, however the Oni goes after Callie instead, and then bites her.
Luba finds a note regarding "ideal subjects" and "SpyOnis", and finds out why Niki was kidnapped; they needed a perfect subject that knows about fears of the Oni to humans. However, Luba is unaware that the Oni is behind her. Bravely with a holy dagger, she slashes it at the Oni mercilessly. The Oni is killed, and the dagger breaks. However, she sees something shiny that looks to be a keycard inside the Oni. Taking it out, it says it goes to the secret laboratory.
Aubrey gets back up from the window with Jack and Steve rescued. Callie returns saying that she was bitten by the Oni on her arm. She shows her bandaged arm, however that wasn't enough; the Onis had an infection which takes 36 hours to 48 hours for the victim to mutate. Luba tells that she has a keycard to a secret lab.
Following the coordinates, they end up in a completely different room, and in the end of the hall were machines and Onis. Yao was there as well. Yao asks the gang why don't they give up at all. Luba says that they are the blessed heroes of Zydona, and yet they cannot give up till EVIL gives up. Aubrey gives Luba an executioner's cross. With it, she kills all of the onis and saves Niki, but Yao has escaped.
At the back door leads to a secret route that Yao may've escaped, to the forest. Reading a sign, there leads a cabin called "Xander Cabin".
Following the trail to Xander Cabin, Luba knocks, but there is no answer, but the door is unlocked. She finds notes regarding Onis' arrival and the victims of the Onis that were already killed. Yao runs past a gate with a sign that says "DANGER: DO NOT ENTER". Luba tries to budge the gates, but they won't open.
Climbing over the gate, they come across a lake labeled "Project Aquarius"....
