Revisiting the Deep Sea

Liban Icon.png Seafloor City Guide: "——Everyone from the Kingdom, once we ride this current, we'll soon arrive at Kralhu-sama's Seafloor City~♪"

Anna NPC Icon 1.png Anna: "Thank you for guiding us, Liban-san. Thanks to you, we came this far without any large incidents."

Picky Icon.png Picky: "Eeh, our trip was a chapter of incidents! Getting used to breathing underwater was such a traumatic experience; even now, I feel like I'm gonna drown at any moment, uuuugh..."

Liban Icon.png Liban: "Since you hail from the dry land, being able to breath underwater through the sea miko's special technique may be a mysterious experience."

Liban: "But Picky-sama, I believe you've grown quite adept at swimming compared to at first~♪"

Picky Icon.png Picky: "Eh, it looks that way? Fufu—n, I heard we were going to be meeting Kralhu-san on a regular basis, so I started practising my swimming in secret—!"

Shadia Icon.png Shadia: "That said, compared to on land, there's no helping our movements being slow... Because of this 'water pressure', it's also having an impact on our health.."

Picky Icon.png Picky: "Ah—, now that I'm bubbling with enjoyment, I do feel like my health is depleting little by little, but..."

Liban Icon.png Liban: "Fufufu, I hear the deep sea and land are going to be walking with hand and fin clasped together. So please get used to being underwater in the meanwhile."

Liban: "Now then, now then, the Seafloor City is going to be coming into view——eh, huh...? Something looks like it's coming towards us...?"

Ibuki Icon.png Ibuki: "Hmm, a team of armed Merfolk, eh? Somehow, it doesn't look like they want to chat. Prince, it would be best if we prepare for engagement."

Picky Icon.png Picky: "M, Master Priiince! Some of them are swimming from over there. This is a battle underwater, so watch out for them!!"

Ibuki Icon.png Ibuki: "Indeed, it'll be difficult blocking them directly since we're not walking, but rather swimming along the ocean's floor. Prince, focus on dealing with them from afar."

Liban Icon.png Liban: "Uugh, this was supposed to be a safe route... Dry Lander Prince-sama, I beg of you, please lend us your strength!"


Merman Icon.png Merman: "——Yosh, completed our reconnaissance of their military strength. Let's hastily make our own individual retreats. We'll report our Prince intel to Gaghiel-sama."

Ibuki Icon.png Ibuki: "Kuh... As expected of Merfolk. They seem to be quite fast when making their retreat underwater."

Shadia Icon.png Shadia: "Liban, I believe you said this route was supposed to be safe?"

Liban Icon.png Liban: "I, I did. That's because this route is being periodically patrolled by the skilled guards of the Seafloor City."

Shadia Icon.png Shadia: "... Those guards not being here is also peculiar. Prince, something may be afoot in Kralhu-dono's Seafloor City."

Picky Icon.png Picky: "Eeehh, b, but isn't Kralhu-san the super strong octopus-san that used to be a former Maou Army Executive!? I, I believe he'll be fine, surely!"

Shadia Icon.png Shadia: "Like you said Picky, do you believe a super strong former executive would allow the enemy to swim into their territory? ... This may not be some chance encounter."

Liban Icon.png Liban: "No way... We have to return to the Seafloor City at once! We have to quickly request reinforcements from the other merfolk as well, and umm, errr! What should we do...!?"

Anna NPC Icon 1.png Anna: "Please calm down, Liban-san. If it's reinforcements, they're right here."

Liban Icon.png Liban: "Ehh, h, having you help right now...? I heard from Kralhu-sama all you dry landers are important guests, but..."

Shadia Icon.png Shadia: "Before we're guests, we're comrades fighting alongside each other. Prince, even now, looks like he's about to rush out to help. This man has a staunch character."

Prince Icon.png Prince: "......... (Nod)."

Liban Icon.png Liban: "Prince-sama...! ... *Sob*, understood. I'll guide you to the Seafloor City through the shortest route!!"

Anna NPC Icon 2.png Anna: "Though we meant to have a meeting on how to deal with Tenkai, but it was a good thing we came armed. Prince, let's quickly head to the Seafloor City!"
