Half-Blood Sensei (Mairimashita Iruma-Kun Male OC)

*Special* Trio's Vacation

~Hikaru's POV~

The exams are over, I was chilling back at the mansion in my room. It was a break for all the students right now but I was bored. Right now I'm losing very badly at chess with Opera.
Hikaru: Ah! I lost again!
Opera: You're smart, but I'm just better Hikaru-sama.
Hikaru: Damn it!
I sigh at my losing streak.
Hikaru: I'm bored Opera....
Opera: You don't want to play anymore?
Hikaru: Not really...
Opera: Why not go have fun with Balam or Kalego?
Hikaru: I would love to bother them but I have no idea where to take them.

   Opera was thinking for a second and then hands something to me.
Hikaru: What this? Aquacase?
Opera: It's an aquarium in the demon world, it's also what you humans called a water park too.
Hikaru: An aquarium and a water park!
   I got excited, back in the human world, I never got a chance to visit either of those things
Hikaru: I'm calling them right now!
   I decided to call Balam first.

~Phone call~

Balam: Hikaru-kun? Hello.
Hikaru: Chirou-kun! Do you want to hang out with me to Aquacase!?
Balam: Aquacase? Oh! That's the famous aquarium. I would love to go, I want to see the unique creatures.
Hikaru: Okay, see you tomorrow!

   I called Kalego now.

Kalego: What do you want?
Hikaru: Eggo-kun! Please come to Aquacase with Balam and I!
Kalego: No.
Hikaru: Eh?! Why not meany Eggo-kun?!
Kalego: I do not enjoy loud places with little brats. Why would I want to spend my break with you?
Hikaru: Pleeease Eggo-kun!
Kalego: No.
Hikaru: U-Um, what if I do your work for you?
Kalego: ...How much work?
Hikaru: I'll do one month's worth of our battler's paper work!
Kalego: ...Fine. After break you will immediately start it.
Hikaru: I will! I promise Eggo-kun! Meet up at Aquacase tomorrow!
Kalego: Good bye.

   I cheered, this is the first time all of us hangs out outside of school! I suddenly realize something.
Hikaru: What do you bring to a water park?
Opera: If you want, I could help you pack.
Hikaru: Yes please~!

~3rd Person's POV~

   Sullivan and Opera greeted Hikaru goodbye. Hikaru excitedly goes to Aquacase and was the first one to arrive.
Hikaru: First~! Now time to wait for Chirou-kun and Eggo-kun.
Hikaru was playing on his phone until he heard a familiar voice.
Balam: Hikaru-kun.
Hikaru's eyes lit up and goes to hug Balam.
Hikaru: Chirou-kun~! You look so adorable!
Balam: Good to see you too. Is Kalego-kun here?
Hikaru: Eggo-kun is coming soon. Once we get to the pool area, I'm just gonna gently shove him in~!
Suddenly he felt a hand grab his head.
Kalego: Who's going to shove me?

Kalego squeezes, causing Hikaru to squeal in pain.
Hikaru: Ow! S-Sorry Eggo-kun! L-Let go please!!
   Kalego reluctantly let's go of Hikaru's head. Hikaru squats down in pain while pouting.
Hikaru: Meany!
Kalego: Childish.
   The two glare at each other, making Balam sigh at their childish antics.
Balam: Stop glaring at each other and let's head in already.
   They listened to Balam and head through the entrance together. Once inside, Hikaru started getting excited over the beautiful sight. It was a long glass tunnel surrounded by water. Balam was staring at the sea creatures while Kalego was bored.
Hikaru: Oh my gosh! It's so pretty!
Balam: Such fascinating creatures.
Kalego: Eh, it's alright.

   Hikaru never seen the underworlds aquatic creatures. He mostly stayed in the mansion.
Hikaru: Chirou-kun, what's that?!
Hikaru pointed at a creature.
Balam: That's an exotic species. It's beautiful scales attract predators easily, making them quite rare with their lower populations.
Hikaru: And that?
Balam: That species is on of the most poisonous aquatic creatures. One prick from its fin and you'll be in a coma.
Balam keeps explaining each creature with many facts, attracting the other demons who were curious. Now Balam is crowded around with listening demons, he's acting like a info guide. Hikaru and Kalego were out of the crowd, staring at Balam.
Hikaru: ...I didn't think this will be a fish tour.
Kalego: Once you get Balam going, he will not stop for a while.
Hikaru shouts at Balam.
Hikaru: Chirou-kun! Do you wanna head to the pool?!
Balam shouts back.
Balam: It's okay! I'll catch up with you two later! Go have fun!
