”Mainstream" was created to bring their favorite HipHop into the mainstream of J-pop. The story is that from debut to Mainstream was a master plan that was made from the beginning. Their official channel is a treasure chest and you will enjoy watching any of them!😆

こちらも見てほしかったので嬉しかったです🤗

リアクションありがとう😊日本🇯🇵でとても人気があるグループです。

Mainstream！これは最高です！ありがとう！

Thank you again for reaction to BE:FIRST so quickly! I'm glad you watched “Mainstream”(even if it was unintentional). “Masterplan” music video is another master piece. They all sing and rap. They do rap cypher in “Milli Billi” special dance performance video.

It was fun reaction. All members can play main vocals and rap. Be: first reaction. Members say they were ready for the world.

Thank you for reacting to Mainstream! If you thought this MV is insane, you must watch MV for Masterplan too! 😎 The low-voice rapper is SOTA, who has also co-choreographed the dance for both Mainstream and Masterplan. His dance moves are crazy, no wonder so many dancer KZfaqrs are talking about their dancing 🕺They are also known for their singing skills, especially when it comes to live performance - they use handheld microphones to sing (without lip sync) while dancing so hard! Hope you get to watch some of their live stage videos in the official channel 😊

🎌❤️ Milli-Billi🔥🔥🔥 Scream🔥🔥🔥

MainstreamのReactionありがとうございます😊MasterplanのMVも観てくださいね

BE:FIRST🇯🇵❤

リアクションありがとうございます❤ 彼らはこのダンスをしながらハンドマイクで歌を完璧に歌います。 歌声も個性的ですがそこが魅力的です。メンバーのSOTAはコレオを考えており、ダンスは世界一の実績があります。デビューからずっと進化を続けている目が離せないアーティストです。 是非、他の曲もチェックしてみてください。

🇯🇵❤早速のリアクションありがとう😄❣とても嬉しいです☺🎶他のMVもチェックしてくださっていると思うので是非次のリアクション楽しみに待っていますね🤗💖

Thank you for reacting. I like your editing, it's so interesting😆 I recommend you to react to their songs like "Milli-Billi", "Scream" & "Boom Boom Back". All of them are good at singing, dancing and rapping. Also, you could go back to their debut song "Gifted.", cannot miss the dance practice.😊

Thank you for responding to my request！ Please give us the reaction of "Milli Billi" and "BoomBoomBack" as well！ I'm sure there will be a lot of feedback from Japanese fans(⁠ ⁠ꈍ⁠ᴗ⁠ꈍ⁠)

❤ありがとうございます(σ≧▽≦)σ🎶🕺🎶✨

そうです、このグループにはロボットが紛れています🤖 リアクションありがとう🫶🫶🇯🇵✨

thank you.Recent music videos are made with a lot of money and are very well made.However, when they debuted, the company was just established and they had no budget, so things were simple, but their dancing and singing are amazing, so I would be thrilled if you could watch and listen to their various songs.

Thank you❤BE:FIRSTのリアクションありがとうございます♪😊

“Masterplan” and “Mainstream” fonts are also the same, so you might mistake them.😅 But I'm glad that you can also watch Mainstream! The actual live footage is even more exciting! Please watch BE:FIRST a lot!

2:35 jajajaja fue tan divertido, exactamente esa fue mi cara la primera vez que vi y escuché Mainstream. Estos chicos son geniales, me gustan muchísimo, tienen un control de su cuerpo y los movimientos, quisiera bailar como ellos ; ; Gracias por reaccionar.

リアクションとても嬉しいです! BEFIRST彼らは全員がメインボーカルでありダンスもラップもします。 歌詞を作り自分達でクリエイトするのです!　もっともっと彼らの曲を知って欲しいです😊😊😊

早速main streamのreaction 有難う御座います❤ 彼等はJPOPの中のトップを目指して努力を重ねている所です。 ダンスのreactionも宜しくお願いします❤

Thank you so much for reacting on BE:FIRST so soon after "Masterplan"🥰 BE:FIRST is the best artists group in Japan!!!(Well,my opinion) I also want you to check out the dance practice version of "Mainstream"🥰 It's just AWSOME!!

BE:FIRST再びリアクションありがとう❣️ 彼らのダンスは素晴らしいです、全てのダンスプラクティスをお勧めします！👍✨ ❤😊🇯🇵

またまたリアクションありがとう♪ 初めてこのMVを観た時はとても驚きました。 同じ様に反応してくれて嬉しかったです！ 彼らは歌もラップも全員素晴らしいです！ そしてハンドマイクで歌いなから踊るのですから凄すぎます！

😊😊😊😊😊😊😊

I like your dance, though😂

Your reaction is the best👍 I am laughing🤣　I recommend there live performance.Please react SCREAM.

You got that right! 💯 BE:FIRST is the BEST vocal & dance group! 🥇🏆 ALL 7 members are main vocalists, rap and none of them sounds alike. They all have distinguished vocal sounds and dance flavors. But their chemistry is incredible and when their sounds and dance mixed, that creates the top-notch BE:FIRST sound and performance‼️ I’ve never seen any artists like them! BE:FIRST is truly one of a kind, and they are high quality live performers‼️

リアクションが最高でした！驚いたり踊ったりしたところが同じで思わず笑っちゃいました。

リアクションありがとうございます。LIVEやフェスではバンドでの生歌。もちろんダンスしながらです。最新曲のMasterplanのMVリアクションも楽しみにしています。よろしくお願いします。

Thank you for finding BE:FIRST. There are too many performances that I want you to watch💦💦 Please continue to support them.

🇯🇵❤THANKS I'm glad you called me "the best group in Japan!" The mainstream music video is the best.Their dance was made by their member, SOTA.They sing with a microphone in their hands while performing this difficult dance.The live singing voice is also the best. from:BESTY

Hello🎉 thank you🎉 Japan

All member→main singer, main dancer,main rapper

Masterplan　Mainstream 似てるよね😅 リアクションありがとう✨🇯🇵

I guess you're interested in the transition. Why don’t you check "Betrayal game". I'm sure the transition is so perfect that you'll like it.

Please also react to the music video of the latest work masterPlan.

I'm glad you happened to watch this music video! Like Masterplan, this choreo was created by BE:FIRST member SOTA with world-renowned choreographer ReiNa 🕺 I am also looking forward to your reaction to Masterplan's music video ❤️

Thank you for responding to BE: FIRST! 🇯🇵❤ Please take up XG as well❗️ TAPE#4 WOKE UP ✨new song

I enjoyed your reaction! My recommendation is Betrayal Game from Bye-Good-Bye One-day One Man Show. That performance video was shot 6 months after their debut. They definitely sing without lip-sync.
