Usual caveat applies. I'm very likely to also edit and release a scanlated version of the chapter, but if you want to use my translation, just remember to give credit.
p1
Bossun: Las Christmas
Bossun: Ah gabe oo my hot
(bottom of panel): Singing this song means...!?
Bossun: Bud a very neck ay
Bossun: You gabe ee away~
Himeko: What the hell's with that half-assed way of singing!!
Himeko: If you're gonna sing, then do it right.
Bossun: I'm no good at English, okay!
Himeko: You gonna be alright singing "Silent Night" with everyone tomorrow? What about the English lyrics?
Bossun: Huh?
Bossun: That's no problem.
Bossun: Sil-
Roman: Wait a moment, prince!
Bossun: Eh?
Roman: In manga, if you recklessly use songs, you will have to pay a large sum of money to the JASRAC because of the copyrighted music.
Bossun: Don't say something like that!!
p2
(top right): Chapter 170: Christmas Card, Part 1
(top left): It's a merry x-mas with everyone so festive!
Bossun: Alright, with this, the wall decorations are basically done. All that's left are the decorative LED lights.
Himeko: Wheew, I'm really excited for tomorrow! It's the first time we've loaned out the club room for a Christmas party, it's gonna be fun~
Roman: Who will be coming?
Bossun: Let's see... Me, Himeko, Switch and Roman, of course.
Bossun: Saaya, Captain,
Bossun: Momoka, Dante...
Bossun: Aaand I don't remember his name, but some sort of samurai person.
Himeko: That's cruel.
Bossun: Yuuki-san said she can't come because she's going to a dark arts mass held by the dark arts circle "Cult of the Dark Black Occult."
Himeko: What the heck, that group sounds suspicious.
Himeko: But anyway, I'm really looking forward to this! We're gonna exchange presents too, right?
Bossun: Man, you're really excited, huh.
Himeko: Did you buy presents already? I haven't yet.
Bossun: Me neither. I figured I'd go shopping after this.
Roman: Same here. Parties are always in the second part of the story, so I thought I'd go once this one is over.
Bossun: I just told you not to say stuff like that!!
p3
Switch: Greetings, ladies and gentlemen. It appears you are all present and accounted for.
Himeko: The hell's with him?
Switch: I have come to supply you with the LED light decorations, Bossun.
Switch: A friend whose house is an electric appliances store gave me these that he was planning to throw out.
Bossun: Huh?
Bossun: Wait wait wait! You were on tree duty, weren't you?
Switch: Hm? Wasn't that your responsibility?
Bossun: No, no, I said I was handling the lights!
Bossun: Take a look. I brought the lights we used last year to decorate our tree at home.
Himeko: Woah, there's a ton.
Switch: Hrm... I am at fault here. I apologize.
Himeko: Well, it's fine, isn't it? If there's a lot've lights, then you've got a variety! I really like the kind that sparkle like that!
Switch: That is true.
Roman: Yep. Drawing the clubroom full of sparkling lights seems difficult, but that's what assistants are for.
Bossun: Can't you keep quiet!?
Momoka: Everyone-!!
p4
Momoka: I've come to help out~
Himeko: Momoka!!
Bossun: Ooh! It's good to see you again, Momoka!
Momoka: It's been a while, neesan!
Himeko: You really came, Momoka!
Momoka: And Switch...
Momoka: It's been a while.
Roman: It's been a while?
Roman: No, even if you say "it's been a while," in manga almost no time passes.
Roman: In November, you wandered around aimlessly, then after that, because you thought you had finally made progress in December, again you fell into an endless loop.
Roman: Unfortunately, the long-awaited Christmas event takes place in a completely different season than the real one.
Himeko: Wait wait wait! It's pointless to say stuff no one cares about!
Bossun: Shut uuuuuup!!
p5
Momoka: Ah, it's... nice to meet you. I'm...
Roman: Kibitsu Momoka-san, right? I already knew that.
Roman: Actually, this isn't our first meeting since previously, I met you in the volume 5 extra story "Resort Dance."
Bossun: Somebody shut her up!!
Momoka: Oh, I brought something good for you guys, neesan.
Himeko: What's that?
Momoka: Tad~ah!! Here you go, light decorations!!
Bossun: WHAAAAAAT!!
Bossun: Why!? Why'd you bring lights!?
Momoka: Bijutsu-san, who is currently in a drama with me, gave me the ones she didn't need.
Momoka: They were used on TV, so there's a lot of them.
Bossun: We don't need any, we don't need any!!
p6
Momoka: Eh!? You don't want any!?
Bossun: No! It's not that we don't want any, but... well, whatever.
Himeko: It's fine, don't worry about it. I love all that sparkling!
Switch: It looks like this will become a fabulous party. Ha ha ha.
Dante: Stardust of the holy night. (I brought LED lights for decoration.)
Himeko: ENOUGH ALREADY!!
Himeko: You're all morons, ain't ya!! What the hell kinda room would sparkle this much!! Is this a pachinko parlor!!
Himeko: You got any idea how much electricity we'd need for all this!! I really hate stuff that irritates my eyes like that!!
Bossun: Didn't you just say you like that sorta thing!
Himeko: I've had it with your boke chain combo!!
Switch: No, for it to be a successful combo, next some samurai or other would say something like "I have brought decorative lights"...
Himeko: ABSOLUTELY NOT!!
Bossun: There he is--!!
p7
Bossun: Huh?
Roman: Fumi-chan!
Fumi: Ah. Did I come in the middle of something...?
Bossun: Nah, it's fine. What's up?
Fumi: Umm... well.
Fumi: I'll come back later!
Bossun: Wawawawa!! Fumi-chan!?
Momoka: Ah, it's alright. If the decorations are pretty much done, we can head out.
Bossun: Ooh, really?
Momoka: Tomorrow's party starts at 4, right? I'm looking forward to it.
Bossun: Yeah.
Bossun: Later.
Roman: Until the second part!
Himeko: Shut it already!
p8
Fumi: I wish for you all to lend me your strength.
Fumi: I want to
Fumi: Save my friend.
Himeko: Will you tell us about it?
Fumi: Yes.
Fumi: In my class there is a boy named Morino-kun, but...
p9
Fumi: Since the end of summer vacation, he has become a hikikomori.
Fumi: Morino-kun and I grew up in the same town, attended the same middle school, and were members of the same art club.
Fumi: The art club was made up of both boys and girls, and everyone got along well.
Fumi: And so, right around this time last year, the art club held a Christmas party...
p10
Morino: Here you go.
Fumi: What's this...?
Morino: A Christmas card.
Morino: There's one for everyone.
Fumi: Wow!
Girl: This is amazing! Did you make it yourself?
Boy: Ooo, it's completely 3D!
Morino: W...well, a...anyone could make them. The trick to it is easy, so...
Fumi: This tree picture is really good, though!
Fumi: Did you draw this too?
Girl: Eh? Fumi-chan's got a picture of a tree? Mine's Santa.
Girl: I've got a snowman.
Boy: Mine's a dog. What's with that?
Fumi: This tree picture is absolutely amazing.
???: Looks like everyone loves how their images are different.
Narration: Morino-kun was, without a doubt, the best artist in the club...
Morino: They took me a week to make.
Narration: And a very kind person.
p11
Fumi: Ah, that was fun!
Fumi: I hope we can have another Christmas party like this with everyone next year, too.
Morino: Yeah.
Morino: But after graduation, everyone will be split up.
Fumi: Where are you applying? For high school.
Morino: Me?
Morino: I thought I'd go to Kaimei.
Fumi: Me too.
Morino: Heeeh, Kaimei for you too? I figured you would have already been accepted to a higher ranked school.
Fumi: Sa...saying something like that... I'm not smart at all.
Morino: Are you going to join an art club in high school?
Fumi: No.
Fumi: I thought I would join the manga research club... since my drawings are manga-like.
p12
Fumi: I'd like to become a mangaka in the future.
Morino: Heeeeh... it's amazing that you've already got a goal in mind. I'll be rooting for you!
Morino: As for me, there's still nothing...
Fumi: Are you going to join the art club again?
Morino: Yeah.
Morino: Since art is my only redeeming factor.
Morino: I can't do physical activities, and
Morino: I'm bad at making friends... art is all I have.
Morino: In the future, well... I'd like to become an art teacher and work steadily on creating my own art... something like that.
Fumi: ......
Fumi: I'll be rooting for you.
Morino: Ha ha ha, thanks.
Morino: Well, until I've passed the entrance exam, I'll be seeing you.
Fumi: Same here.
p13
Narration: Eventually, Morino-kun and I passed the exam for Kaimei, I joined the manga club and he joined the art club, but...
Boy: Ooh! Just what you'd expect from Kusabe-senpai!
Girl: That's really good, Kusabe-san!
Boy: So awesome! You must be the best in the school, right? Hehehe.
Kusabe: Heh.
Kusabe: Of course I am.
Girl: Woah, you're really skilled!
Teacher: Yes! Considerably so.
Boy: That's great isn't it, Morino!
Girl: You're really good~
Morino: Thanks...
Teacher: You have an outstanding talent.
Morino: S...saying that is a little...
Girl: An amazing first year has joined!
Teacher: You've even already surpassed Kusabe, haven't you?
Morino: That's not...!
Girl: That's right~
Girl: Hey! Kusabe-kun!
p14
Kusabe: ...............yeah, it is........
Morino: ...who would...
Kusabe: I wonder who could've done it~ kukuku...
Kusabe: Don't get so cocky, first year.
p15
Fumi: That senpai left over the summer and isn't in the club anymore, but...
Fumi: Because Morino-kun is such a sensitive person, he was very hurt and disappeared from club activities.
Himeko: That's understandable...
Narration: If that's all that happened, it would be alright. However, since then, whenever he tried to paint at home, he would feel sick, his hands would shake, and he just didn't seem able to at all...
Fumi: For him, it was a huge shock.
Fumi: Something like "I have no worth if I can't paint." ...... since the 2nd term, he even stopped attending school.
Fumi: I've gone to his house to talk with him, but I haven't been able to see him at all.
Fumi: Eventually... the seasons changed...
Bossun: Hrm...
Himeko: We understand.
Fumi: I want to help Morino-kun by any means possible!
Fumi: He shouldn't have to worry about what some cruel person does!!
Fumi: I want to show him that there are many, many fun things about school!!
p16
Fumi: Please take a look at this. It's the Christmas card Morino-kun gave me last year.
Fumi: To think that the person who created such wonderful art now finds holding a brush to be painful...
Bossun: Nice.
Himeko: It really is.
Fumi: I... think in order for him to return to school, he has to get to a point where he is able to paint again.
Fumi: So...
Fumi: I want to get him out of his house.
Fumi: Even if just one step.
p17
Bossun: A hikikomori, huh...
Bossun: That's a tough one, Fumi-chan.
Bossun: It's a delicate problem, and would even be tough for a specialist.
Bossun: And that time with a certain someone was pretty serious too~
Bossun: What do you say,
Bossun: Switch.
Switch: Yeah.
Switch: Fumi-chan,
Switch: In my freshman year, I was a hikikomori.
p18
Switch: But
Switch: I was saved.
Switch: Somehow, by a certain someone.
Switch: Let's do it,
Switch: Bossun.
Switch: Since it's us, there will be something we can do.
