It was a seemingly normal day for Mob: get ready, go to school, get through classes, and ignore Asagiri as best as he can. His day hadn't been anything out of the ordinary. That was until his last class of the day.

Mob was drifting in and out of sleep during chemistry, when he hears his teacher's voice boom over the chattering students, "Alright class, I have a special announcement!"

Teru, who was sitting in the chair next to him, beings to (not so quietly) whisper to Mob "This is interesting...What do you think the so called 'special announcement' will be about?"

Tome replies, twisting her body around from the table infront "He's probably over exaggerating and it's going to be that we've been given some new science equipment or something."

"To be fair we do need more science equipment."

Tome and Teru continue to whisper-talk while Mob is trying to listen to whatever the teacher is rambling on about, so that he can acctually find out what the 'special announcement' was. Just as their conversation begins to die down, the chemistry teacher finally get to the point of his long, drawn out speech.

"We're going on a field trip to..." he drums his fingers dramatically against his desk, "Spirit Tower!" the teacher exclaims enthusiastically.

"This could only happen to you Shigeo, only you." Dimple grins as he rolls around the air howling.

"Oh." is all Mob says, but as the students errupt with excitement, Mob is utterly confused. Shishou's tower? Why would people want to go there out of all places? Of course it's cool, I mean Mob literally lives there, but it isn't like Reigen is famous or anything..?

Teru halts Mob's train of thought to a stop with animated actions, "Kageyama, we're headed to your master's tower, how cool is that?"

Mob replies, still clueless "Yes but why is everyone so excited for this?"

A dumbfounded Teru does not have the heart to explain that the Mystics are the most famous people on earth, so he sweetly replies "It's alright Kageyama, don't worry about it."

Dimple, who was still trying to contain his laughter mutters "God, kid how oblivious are you?" Which earns him a subtle yet painful pinch from Teru.

Their chemistry teacher calms the class, and explains that both third and second years are going on this trip, and it's happening this Friday. The bell rings after what felt like hours of chemistry, so Mob and Tome say their goodbyes to Teru and make their way over to the hall for decathalon practice.

As they arrive at the hall, everyone is still jittering with enthusiasm about the recently announced field trip, yet even with the loud chatter echoing around the hall, Asagiri spots Mob from her corner near the wall. "Hey loser! You ready for your stupid lies to be exposed?"

Mob, who is confused as to what he'd be lying about, replies "But I'm not lying about anything?"

"Yeah and I'm part of the Mystics." she scoffs back.

Mob, who was used to Asaigiri's antics, simply ignores her teasing and continued to set his bag down ready for practice. However, Dimple and Tome were not. As Tome is giving Asagiri looks that could kill the entirety of Claw, Dimple is shouting "Let me at her Shigeo! Let me at her!" whilst waving his arms about and being held back by the smallest trace of Mob's power.

The rest of practice continues on as usual, only with a few extra snide comments than necessary from Asagiri, and Dimple begging to possess her every five minutes. Eventually, Onigawara declares the end of practice for today, and the team part ways and begin on their journey home.

Mob enters the building he's called home for years now through the entrance only certain people were allowed through. The moment he steps through to the penthouse, the atmosphere is strangle calm. Reigen was working on something 'important' on his computer (slither.io) with Serizawa watching him in awe (Reigen had managed to get first place and didn't seem to be losing anytime soon). Koyama and Sakurai were playing smash Bros, it had been a draw so far, so the game was starting to get slightly heated. Mob didn't want to get involved with their bickering for the 10th time this week on who is the 'ultimate smash Bros pro', so he left them alone. Finally, Muraki and Tsuchiya were having a seemingly nice conversation about their last fight against some random spirit that appeared the other day. Overall, it seemed surprisingly domestic for a worldwide team of esper heroes.

Mob makes his way over to Reigen, setting his bag down and rummaging through it for the plain looking slip of paper. Reigen, as nosy as ever, peeps his head away from his 'very important work' to see Mob.

"Hey Mob! what are you looking for?"

"Hi shishou, I'm looking for the permission slip to come here on Friday." Mob nonchalantly replies, which in turn seems to get the attention of everyone in the room.

"I'm sorry you said to come here? Why would you need permission for that?" Reigen questions, seemingly shocked and completely forgotten about his computer.

Serizawa then squeaks and the discarded snake is eaten by the other players.

"Yeah Mob, your room is down the hall, in what world would you need that for?" Koyama adds, still too focused on winning to lose his attention just yet.

Mob, who finally finds the crumpled paper, pulls it out of his bag and hands it over to Reigen. Dimple begins to deviously laugh, as Reigen's face turns from one of confusion, to something of shock and amusement. He then starts laughing along with Dimple, with his eyes beginning to tear up from laughing so much.

The others (including Mob) stare at Reigen with confusion. The man in question waves his hand for everyone to come over to see the sheer irony of this seemingly hilarious piece of paper. They read the title "FIELD TRIP TO: SPIRIT TOWER" and that's all it took for the room to burst out with laughter, everyone but Shigeo giggling from the ironic field trip the confused middle schooler will be going on.

Eventually, everyone somewhat calms down from the laughing fit, and explain to a very oblivious Shigeo Kageyama, that this is a golden opportunity to show his classmates (in Reigen's words) how great of a kid he is, and show that you know THE Reigen Arataka, Greatest Psychic of the 21st Century! Because of Reigen's (not so) great explanation, Mob realises he could show his classmates how cool and smart his shishou is!

...

Similarly to Teru, none of the Mystics have the heart to tell Mob that mostly everyone in the world does infact know this information, with Reigen being one of the most famous people in the world, and decide to let Mob stay in his little bubble.

The rest of that day goes thankfully normal for Mob, the only difference from his usual day being the new information of the field trip, which in Mob's mind won't change anything. Oh how wrong he is..
