In the vicinity of Insect dungeon a teal-haired girl looking around trying to find out where she is now. The girl still remembered her name is Wriggle but, she feel there's something different about the forest. She thought to herself perhaps it's the air that made her think that or perhaps it's the tree but her memories are not something she could rely on, so maybe it's just her feeling. Suddenly Wriggle remembered everything that is happening before her transformation.

"Ugh, so that's what happened." Wriggle said to herself.

Wriggle look down at her clothes and feel unsatisfied. The clothes that she is wearing now are a brown woolen shirt that is too large for her and the pants is slipped and her important part could be seen if it's not covered by the shirt. She sighed since this clothes isn't what she usually wearing and not comfortable to her.

"If I remember correctly to get clothes, the human said 'Status Open'."

A status panel is showing up in front of Wriggle and made her jumped back in surprise.

"That surprised me, then after said that this thing showing up," Wriggle said. "Now I touch this part of this thing."

Wriggle touched the item tab in the status panel then it change to list of items but, unlike before the transformation where there's a lot of thing that showing up, it's only showing her cloth.

"Oh, there it is my cloth, now I just need to touch it."

A bright light covering her entire body and after it died down the brown shirt is disappeared and she is instantly wearing a white shirt that perfectly fit her, black cape with red lining in the shape that look like an insect wing and a baggy blue knee-length shorts.

"Now, I have my cloth. Let's recall what did the human want when he transform into me?" She said.

She reminiscing about before her transformation is happening then a look of disgust showed in her face.

"Really, human you want to control the insect and make them fight to make you stronger. I should have expected this from a human they see us either as entertainment or pest, even though we have an important role in this world," grumbled Wriggle.

While Wriggle still grumbling an insect is flying behind her and landed on her ear. Wriggle feel something landed on her ear so she stopped her grumbling.

Then the insect that landed on her ear said, "My master wanted to meet you, could you go with me to him?"

"Wait, first of all show yourself in front of me, since I want to know what kind of insect you are."

The insect is now flying in front of Wriggle. The insect that fly in front of Wriggle is a ladybug.

"So you are a ladybug, now I want you to tell me the truth what kind is your master?"

"He is an insect."

"Why he want to meet me?"

"I don't know, I'm just told to guide you to him."

"Well, since he is an insect and wanted to meet me then I will go. You could stay on my ear and tell me the direction of your master."

The ladybug then fly back to Wriggle's ear. It then giving Wriggle the direction to where his master is reside. Following the direction, Wriggle reached a place what look like the entrance to cavern. The entrance size is slightly larger than Wriggle and the ground is smooth. Not long after entering, the entrance is buried and the cave is brightened.

"Eh, what's happened?"

"Calm down, that's what supposed to happen now we just need to keep moving straight and descend."

Even after reassured by the lady bug Wriggle still got a little anxious but, he continue to move where the ladybug told her. While on their travel, a lot of insect monsters are lurking around in the corner of the cave. When Wriggle is around the monster will stop and gaze at her. Wriggle didn't get bothered by their stare and continue to keep moving forward.

"Is it still far away?" Wriggle asked

"No, it's near." The ladybug answered.

True to the ladybug word, after walking a little further they are seeing a large light brown double door that made in stone.

When they are in front of the door the ladybug said, "My master is waiting for you inside."

After Wriggle heard it, the feeling that a lady bug rested on her ear is gone. She is looking around confused as to where the ladybug is gone. But before she can find the ladybug the double door is opened, so she decided to go inside. The inside of the room is a wide throne room with a light brown brick. The size of this room make Wriggle think that even if the Oni enlarge herself there's going to be a space for her to move around and even jumping around. Though even the room is wide, there is nothing decorating it. Only a single throne that made in stone located at the very back of this room that could be found. Sitting on it is a giant cockroach monster, but because of his body proportion it more like he standing in front of it.

"Welcome, I have been waiting for you." The cockroach said.

"Waiting for me, What for?"

"When I was doing nothing in this room, somehow I suddenly have a feeling that I want to meet someone above ground and following all her order. Unfortunately I can't get out from this room no matter how much I try. So I decided to send a bug to escort the one that made me feeling like this to here. That feeling is coming from you right?"

"That's probably because of my ability, but I never thought you could feel and affected by it. You are stronger than me right?"

"Yes I had a feeling that I'm definitely stronger than you. Even though I know this is because of your skill I will be loyal to you. So if you need any help you can come to me and I'll gladly help you."

"You said skill right? Could you tell me what it is? Before I transformed, the human have a thought he wanted to use my skill to summon a strong insect but can I even do that?"

"Transformed from human?"

"Yes, weird isn't it even though I'm a firefly youkai I'm transformed from human."

"Youkai? what is that? Though I guess I should answer your question first. Could you say 'Status Open' and then 'Share'."

"Status Open, Share."

Then the status panel is showing and could be seen by both of them. The cockroach then examined Wriggle's Status closely. He could see that she is weaker than him. That made him wonder how could he affected by her, after all his creator, the one that told him all about new information outside have told him that the dungeon monster couldn't be controlled by anyone else other than him. Yet here he is affected by a skill to the point he will rebel to his creator if commanded by her.

"So can I really summon an insect?"

Wriggle question interrupted his train of thought and made him remember, that he is still not giving her answer.

"Yes, it seems you really can summon an insect, try touching the skill name to get more information."

Then Wriggle touched the skill name and the explanation is showing up in front of status panel.

Insect Summoner MAX
The user of this skill could summon any kind of insect with the cost of mana. MAX level removes the duration of the insect summoned by this skill.

Insect Swarm MAX
The user of this skill could duplicate the insect that summoned with only 1/10th original cost to summon it. MAX level removes the duration of the insect summoned by this skill.

Insect Manipulator MAX
The user of this skill could control any kind of insect.

"So I really can summon insect, but how do I use it?" Wriggle asked the cockroach monster.

"Hmm...Usually you just need to think about going to use the skill."

When Wriggle thought using the skill the status panel is changed. The panel now showing an image list of insects and each of them has a number on them.

"Oh, look there's a lot of insect in that thing now," Wriggle said. "So this how I summon insect I thought they will show up not just like this."

"I never knew that status panel could do that. This probably where you select one of them to summon it," The cockroach said. "It seems there are a lot of them, I wonder if I do this"

The cockroach then touched the status panel and swiped up. The image now scrolled down and showing more insects and larger number on them. Because of this he wondered how many insect listed in it and got lost on his train of thought again. Wriggle curious of what the cockroach is doing. When she is going to ask him, he looked very serious so she decided to just watch silently. The cockroach keeps browsing at the list of insects until he saw something in it.

"WHAT!" the cockroach scream.

Wriggle startled when she heard the cockroach scream.

"Ah, I'm sorry to surprise you."

"It's okay, but what make you suddenly screaming?"

"Well, I was curious of how many kind of insect in this and so I scrolled down to see all of the insects that listed here. The lower the image, the bigger the number is and the stronger the insect is. When I see myself in this I inadvertently scream." The cockroach said while pointing at one of the image.

"You mean this one." Wriggle said while touching the Image

Gargantua Cockroach (mana 2707)
A huge Cockroach that has defeated many monsters and lived longer than 100 years will evolve into this monster. Quicker and had more endurance from magic and physical attack than their previous evolution.

"Yes, that is me but, the name and explanation is from the human, I wonder why. Now I look clearly not only me there's even stronger insect than me showing up."

The cockroach is touching one of the insect images, but nothing happened. After Wriggle touching the image the usual explanation box appear.

Ancient Centipede (mana 3830)
A monstrous size centipede, it said that it could cover a hill with it size. The exoskeleton of this monster is very tough and capable to deflect magic. The gut of this monster is highly poisonous and theorized that this monster could use poison-based magic.

"This one has long extinct and considered a fake legend by the humans and there's many similar kind of insects in here too. If you summon even one of them not many of monster today can beat it."

"Heh, that is useful information. But how do I summon them?" Wriggle asked flatly.

Hearing how Wriggle responded, the cockroach is a little bit down. He want to tell her the legend of each of the insect. But since she is not interested he decided to just answering Wriggle question.

"How about you try to thinking about summoning one of the insect?"

Wriggle doing what he said and trying to think about summoning an insect. Then a firefly is appearing in front of her. Wriggle excited to see that the firefly that he wanted to summon is showing up.

"Well, it seems it was successful. Now can I ask you something?" the cockroach said.

"Yes, just ask." Wriggle responded.

"In the status panel Youkai is your race, but what exactly is youkai?"

"I kinda forgot what youkai is, but one of my friend said that youkai's job is to attack human. That's the only thing I could remember."

"Then we're the same, though I only attack human that coming inside this room."

"Really, you attack human too?"

"Not only me the rest of the monster inside this dungeon will attack human, how about I show you the human that now currently in here and see how all the monster react."

After that a multiple box screen appeared in the room. Each screen is showing different adventurer group. Their conversation could be heard when Wriggle is looking at one screen. Then Wriggle change where she is looking. Then she is looking at a screen that is showing 2 female adventurers and 1 male adventurer. When she is hearing their conversation, Wriggle is becoming furious.

"Hey, where are those people right now?"

"So that make you angry, If you want to meet them just go inside that the magic circle and I'll guide you to them." The cockroach said while pointing at the magic circle.


In the square room with yellow light brick three adventurers are fighting against a monster that is look like a worm with gray exoskeleton. The worm exoskeleton is in tatter revealing a pink skin underneath it. The worm is rolling to one of the female adventurer that wearing a red robe.

"Taunt." Another woman adventurer is shouting.

The worm stopped his attack then turned around to the girl that shouting it. Then he is now targeting another female adventure with his rolling attack. Since the worm rolling attack direction is straight forward it misses her when she is moving to the side. The worm stopped it rolling attack when reached the end of the room and tries to turning around again. But before it could do that an explosion magic hit the worm.

Despite get hit by the explosion magic the worm still alive, but the exoskeleton is now showing more it skin and it movement become very slow. Seeing the condition of the worm a male adventurer didn't miss the chance to slash his broadsword to the worm's exposed skin. The worm then let out a shriek and it blood gushed out. After moving wildly for a while, it stopped moving. A magic circle appeared in the room after the worm is dead, seeing it the three adventures let out a relief sigh.

"I...told...you the three of us is enough... to beat this pest." The male adventurer said while panting.

The female adventurer is trying to calm down her breath first before responding to the male adventurer.

"Yeah, you're right but still it's going to be easier if she was here, after all I can't block the attack without her guard magic." The female adventurer that wearing breastplate said.

"My explosion magic is enough," The female mage said. "We don't really need her for this kind of monster."

"Well, since you doubt both of us how about your punishment is carving the monster and get the magic stone inside it." The male adventurer said

"Ugh, fine."

She is now take out the carving knife on her hip and start carving the monster corpse. While she is carving the monster corpse, the other two is chatting with each other. But not for long they heard a scream.

"THERE YOU ARE!"

The three of them turn around and look at the source of sound. What they see is a child pointing at them. The child has antennae on top of her head and it made them wary.

"Why do you teleport me far away from them?" The child said.

"Huh, so I can gather many insects before facing them? I could summon insect so why I should gather this much and I could protect myself if it's again these human."

The three of them are confused to whom she talking to, but when they heard 'gather' the two female adventurers look at the male adventurer. The male adventurer knew this mean they will let him decide what to do next. So he use 'scan' skill to see how many is really gathering since he couldn't see anything other than the child. His expression is showing fear after knowing the result of his skill.

"Leave the corpse and run to teleport magic circle, NOW!" the male commanded to his party.

They confused at first but they believe what the male said and run away to magic circle, following behind them is the male adventurer.

"Ah Wait," Wriggle said. "Grr...It's your fault they now run away before I could tell them the importance of insect."

"I'm sorry I never thought the guy could use 'scan'." The cockroach telepathically said to Wriggle.

"Well, it's fine. But could I chase them if I going to that magic circle?"

"I'm sorry again, but that magic circle couldn't be used by you. Only the party of adventurers that defeated the boss could use it."

"Ugh, then can you tell me where they gone?"

"Right now, they are outside of the dungeon. If you want to chase them I could guide you."

"Then please guide me. As for you," Wriggle pointing at one of the moth monster. "Could you make the insect that gather in here not invisible, so I could introduce them to human and what benefit if they are left alive."

Far away from Wriggle in his own room the cockroach look worried and want to say something about Wriggle plan but seeing she is in bad mood he decided not to.

"So you want meet human while you're going out, then I will tell you the fastest way out while meeting many human."


The insect dungeon as the name implies is a dungeon that one can expected to meet only insect monster. It's treated as a hunting ground for those who want to completed subjugation of insect monster. Even the guild treated this dungeon as a training ground for beginner adventurer.

In this dungeon not many strong monster shows up and its monster is very weak to fire and ice magic. It's said that the party that have a mage that can use fire and ice magic will have easy time in this dungeon and could venture the deepest part of this dungeon. The party that coming inside is always try to challenge themselves how deep they could go until their mage is running out of mana.

In this dungeon sometime an adventurer will meet an insect swarm. The swarm always consisted by the same insect group. The adventurers will said they lucky if they find a swarm consisted only weak insect monsters, since it's the efficient way to kill many insect with just one magic. But today, the swarm that always has the same group of insect is now consisted with many different kind of insect and it's currently chasing a group of adventurer.

"OY! Use stronger fire magic to that swarm." An Adventurer commanded to his companion while running away.

"Are you blind or what?! I have used my strongest magic, but there's a monster inside it that could put it out easily. Just keep running we couldn't defeat that swarm." The companion responded while trying to outrun his companion.

They keep running away from a swarm of insect monster behind them. At first it's only 2 adventurers that running away, but each time they are passed another group of adventurers the number keep increased. Before running away some of them trying to use magic at the swarm, but there's no effect on the swarm movement and number, so they decided to run away too. They keep running and running and not even trying to fight it. Some of the mage in the group is casting buff so everyone didn't get tired even if they run for a long time. Fortunately all of them are managed to exit the dungeon and none got left behind. But even when outside of the dungeon they keep running to the kingdom since they didn't feel safe, even though the insect swarm has stopped chased them when they get out from the dungeon.

At the entrance of the dungeon a lone girl is standing in front of the insect swarm.

"Sigh, I'm thankful that everyone here protecting me and getting angry on my behalf. But all of those human become scared before I could tell them the benefit of insect," Wriggle said. "Yes, I know this is the fault of the first one whom trying to burn me. But it doesn't mean everyone chasing them is a good reaction. At this rate the humans will hate insect more and will tried to exterminate all of them."

"You don't have to worry about us, after all that's what we always do and we're not afraid to be killed. If only I could get out from this room I will probably chased them too." The cockroach telepathically said to Wriggle.

"No, what I mean is the normal insect they will get undeserved hate from human because of this."

"Ah.."

"Sigh, it seems I was right to stop everyone here before you could start rampaging at human settlement. Anyway, I'm sorry but I will leave this dungeon and for everyone don't follow me. I will try to find a peaceful way to make human appreciate insect more." Wriggle said.

Wriggle then walk outside of the dungeon. The sky is bright and the sun is still up. Wriggle sighed and thought that this isn't the right time for youkai to active. So she decided to just rest somewhere and think about it later.


Another author note :

So this chapter will decide the rule of transformation and leveling,

for the leveling part I really need to rewrite Yukari condition since I don't want to keep track individual youkai level I will make them all the same level as the MC.

for the transformation part this is the rule that I should keep : "He won't take control any of touhou character until I said so"
what I mean is, the touhou character will control their own body not him. he will can control the body of course until I said so (sorry, can't find another excuse). and this is reason I do a rewrite. why? at first Wriggle going to attack the adventurer that fight the worm, but then I remembered Wriggle won't kick and punch to kill you she will send many of the insect that she could control to swarm and kill you.

but then what about Rumia and Koishi? well... for Koishi the reason is she unconscious so only when she think it interesting is the time when she could control the body. for rumia... well..., I don't find anything that Rumia want in canon. in canon Rumia just wondered aimlessly at day and night. of course she will attack when she could see.

actually the transformation rule is decided at one point of the story ahead, there's one touhou character that I want to write and keep replayed in my head. Though sadly with my pace before I could even write her, real life will hit me first after all my job contract ended at june so after that month if it's not renewed or I found another job. this story will probably ended in long Hiatus. so sorry in advance.
