Preparing for the Birthday Party Stream

You helped me out big time, you two! I got back here late because I was guiding a kid who was lost.

So that’s what got your outfit frayed a li’l. Sheesh, you never change, do ya.

Thanks for patching it up for me, Kiryu~♪ And Kanata, thank you for the drink!

chiaki was dripping with sweat, after all. we cannot have you dry up.

While it’s a good thing to help others, today’ll just go to waste if the main lead in question collapses. Make sure you rely on us, at least for today, aight?

Got it! With you two around, I have the strength of a hundred people! It’s time to head into the main show with the most flawless set-up! ☆

Start of the Birthday Party Stream

“The burning heart Morisawa Chiaki has arrived! Thank you all for coming to my birthday stream today! ☆”

“The screen’s filled up with so many comments wishing me a happy birthday! I assure you all that your passionate feelings are crystal clear to me!”

“No matter how many times my birthday comes by, I’m always happy to have my birthday celebrated like this.”

“I’ll turn all the love you’ve given me into powah, so that I can bring you all energy with all my might!”

“I’ve called over some reassuring comrades today. I hope we can all enjoy ourselves together until the very end…☆”

During the Birthday Party Stream 1

“Happy birthday, Morisawa. Huh, I wonder how many times I’ve celebrated your birthday like this?”

“Thank you, Kiryu! No matter how many times it’s been, the happiness I feel when you celebrate my birthday is exceptional!”

“Haha, that so? Aight, what sorta year d’ya wanna make this one?”

“I’d like to make this my most fired up year yet, of course! Now that I’ve grown older, I want to increase the amount of things I can protect!”

“That’s just like ya, huh? Sounds good to me. Break a leg out there without goin’ too far.”

“Yeah! I’ll keep firing myself up even further as a dependable hero! ☆”

During the Birthday Party Stream 2

“I got pretty blue-colored bath salt from Kanata, that look just like the ocean!”

“yes. chiaki is always dripping with sweat, so i got this in hopes that you take it slow and relax yourself in the [bath]~♪”

“Thank you! I’ll do special endurance training where I soak myself in hot water until my very limit!”

“no, not like that~ you always go for [special training] for anything, don’t you, chiaki…”

“Mh, right! It’s important that I also rest… I’ll stay put for today and soothe myself.”

“yes, okay. i want chiaki to continue being [energetic] forevermore, after all…♪”

During the Birthday Party Stream 3

“This stream is almost over! There are still so many things I’d love to talk about, but I’ll leave it for another time.”

“I was supposed to be the one to bring you all energy today, but I ended up getting energeized by everyone instead.”

“So many people are happy to celebrate the day I was born alongside me. I’m truly so blessed!”

“I won’t suddenly grow stronger just because I’ve grown a year older now. That’s why I intend to keep taking steps forward bit by bit from tomorrow onwards, as well!”

“I’ll make sure to become even more reliable than ever before, so that I rush over to those in need with just as much reassurance! Thank you for today, truly! ☆”
