Today is Indonesia's independence day! And today is also my big sister's birthday as well!

Glory to the Mother Pertiwi!🗿🇮🇩

A drawing I made for Indonesia's 77th independence day in 2022, featuring Soviet ChS4T locomotive, JŽ 661 "Mihaela" locomotive, and JŽ 664 "Ljubica" locomotive. I also made some OCs in this drawing, which are Daniela Misdinoffsen "Dani" (next to a saluting Soviet soldier and JŽ 664 locomotive), Mihaela Misdijević "Mimi" (above Dani), Željka Misdijević "Jemima" (above a counterfeit Trihadi Birawa soldier (grey guy)), and Kazuna Zadornović (next to the grey guy). I also featuring both my online friend and my middle school friend, such as Simon Hendrickson (an online friend, next to Kazuna) and Dzuhri Ghani (playing broom as fake wizard, below the ChS4T locomotive). And I also drew 4 (or maybe 5) former bullies because I was still having problems with them until now, lmao.

Happy Pancasila day!

#Touhou #東方Project #PancasilaDay #HariPancasila
Today's Pancasila day! And I drew Mama Yuyuko from Touhou project, with a ZSU-23-4 "shilka" anti-aircraft tank! And also, there's a running Albanian soldier below the shilka tank, because I suppose it's funny, lmao. (I drew this 3 years ago, lmao)

Galuh Monika Klara Aurelia Parman, the 3rd daughter of Karl Markus Günther Parman and Hjördis Parman (nee Jörgensen), was born in Wonosobo, 6th Januari 2002. Her late dad was a Javanese-German, while her mom is a pure Swede. She currently lives in Flensburg, GDR (German Democratic Republic), together with her eldest brother (Gatot Markus Georg Antonius Parman (born 1996)) and her sister-in-law (Gertrude Immanuella Bertha Parman (nee Göring) (born 1990)) in a mansion. She has 2 nephews and 2 nieces from her eldest brother. She currently works as an intercity train commander (although she occasionally works as a freight train commander too), following her late dad's path as a train commander, in Deutsche Reichsbahn (since September 2024) and PT KAI (until September 2024). She uses her late dad's legacy M62 locomotive and twin version of the same locomotive (2M62) as her flagship locomotive.

I almost forgot about the 3rd batch of 6th March's adventure in 19th Comifuro in ICE BSD, lmao

(Yeah, batch 3)
Venturing with his Wehrmacht friend, 6th March met Sorai Saki wandering without his/her friends. And because this Saki had no voice yet (Nexon haven't yet making Southeastern Asian branch office in this story, lmao), so, beside couldn't obtain his/her Instagram, he couldn't confirm if this Saki is real girl or a guy crossdressing as Saki.🗿 After meeting Saki, 6th March meets the first president of Indonesia, Soekarno! (Let's pretend that this is real, using our own imagination, lmao) After he met President Soekarno, when going to food court located close to concert area with the same Wehrmacht friend, 6th March encountered a half-phantom guy (yeah, this guy crossdresses as Youmu Konpaku) near the place where he encountered Remilia and Patchouli. Several seconds after he met Youmu, 6th March spotted Ichika Nakamasa patrolling around the same place. So he decided to have fun together with her (though only taking photos with her, lmao), and enforcing justice and peace together for a while.🗿

Another photos about 6th March's adventure in 19th Comifuro, 10th Nopember 2024.

(Batch 2)
When 6th March had finished making a gruppa photo(s) with his tactical cosplayer friends, he met a strayed rabbit-girl named Tewi Inaba, wandering with her friend, Eirin Yagakoro. It's suddenly rain! So 6th March and his comrades decided to re-enter the ICE BSD building to avoid being wet (no puns, but you know what I meant). And when he and another friend wandering inside, they found the flagship battleship of "Mangun Utomo" fleet, KRI Atago.🗿 After a momento, after 6th March having lunches with tactical cosplayer friends, he went to an Uma Musume booth on another side of the ICE BSD building. At there, he found Orvefre was sleeping peacefully, and his friends messes him up. Getting an unique idea, 6th March decided to sleep together with Orvefre, and taking a photo of him sleeps peacefully together. (No cuddling, unfortunately)😔🗿 At the same time, 6th March also encountered transcend, the "𝓯𝓻𝓮𝓪𝓴𝔂" horse-boy, when he visited the Uma Musume booth.

Forgot to post this lmao

These are the results from visiting 19th Comifuro in 10th Nopember. And prehaps I'll post more batches of my activities in Comifuro here too.

(Batch 1)
Le Mathias the Norwegian SpetsNaz soldier with Miyako Tsukiyuki aka RABBIT 1 from Blue Archive game. While walking deeper into the convention site, Mathias (me) found Maribel Hearn from Touhou are having an unique conversation (I suppose) with Remilia Scarlett and her servant, Patchouli Knowledge (from Touhou too, lmao) This is Mathias's new deer girlfriend, eh, nope, deer friend, Noko-tan!🗿 Looking for his other friends, Mathias found Astolfo preparing for something near the concert area. Hmm, what is Astolfo doing?🤔🤨🗿
