Unlike the majority of other virtual Youtubers, the people behind Siro and the reasons to create her are pretty straightforward: her first two videos were uploaded to promote a Japanese web platform called DanceStream, where people can browse hundreds of videos of people and animated characters dancing. The Japanese company behind DanceStream is App Land Inc., known for offering solutions in terms of app design and development.

Although they could have hired professional dancers and call it a day, creating a 3D character to promote DanceStream's animation channel is pretty clever. Also, it was perfect timing to jump on the virtual Youtubers' bandwagon! So it was that App Land created profiles on YouTube and Twitter and Siro began to gain notoriety, with a third video in which she launched her career as an aspiring virtual idol.

Now fully voiced, Siro caught people's attention for being a little different than other virtual —and even real— Youtubers: she speaks calmly, she doesn't overreact that much and she sounds rather natural. Another thing that differentiates Siro from the rest is that she usually appears wearing different outfits, which evidently means a much more careful work when creating her 3D models.

Like we said before, Siro's main goal is to become an idol, but this doesn't mean she only uploads videos of her dancing and singing. Being App Land so related to video games and technology, it shouldn't be a surprise to find gameplay videos of both conventional video games and VR software. A big chunk of Siro's content is Siro herself playing PUBG, Mario Tennis Aces, Little Nightmares, Dragon Quest Rivals, Bloodborne and a whole lot of other popular titles.

Aside from other videos where Siro talks about herself to help us know her more, you can even find English and German lessons for beginners, and Japanese people really enjoy that. Her pronunciation is not that bad either! In addition to creating content for YouTube and Niconico, Siro also live streams for fans in VR Live, a VR platform created by... guess who? Yes, another project by App Land!

Another thing you can find in Siro’s channel is a fair share of collab videos, mainly as a way to grow her audience and help other less-known virtual Youtubers. That leads us to talk about ".Lead", a club composed of other 13 members, as for example Kitakami Futaba, Karuro Pino or Baacharu, the virtual horse. Oh, and here's the final test: who are the managers of .Lead? You got it! Apple Land. Siro is not only .Live's leader but also one of the top 5 virtual Youtubers in the world, so as a part of the "4 heavenly kings" —the 4 heavenly kings are 5 virtual girls, but ignore that— she naturally has some videos with the other girls on this group: Nekomasu, Kizuna Ai, Mirai Akari and Kaguya Luna.

While mass popularity is only a dream for most people involved in the world of virtual Youtubers, Siro has already achieved a lot of things in a little more than a year. For example, a few months ago Good Smile Company announced the future production of a Siro-inspired Nendoroid model, while Tokyo Otaku Mode and Kotobukiya presented a 1/7 Scale Siro PVC figure prototype. We'll be able to have our very own little Siro's at home very soon!

Siro and Kizuna Ai are the only ones with both Japanese and English Line stamps, although Ai has two sets and Siro has one, which she shares with other .Live club friends. Just a few days ago, Ikebukuro-based Nicocafe did a collaboration with Siro so for 10 days, people could visit Nicocafe only to enjoy Siro-themed food and drinks or hang out around Siro decorations. Sure, a bunch of virtual Youtubers have made appearances at mass events and conventions, with Kizuna Ai as the most popular VTuber. However, Siro is more than just merchandising…
