STEINS;GATE RE:BOOT Luka Urushibara
Polite, earnest, and easier to underestimate than the lab’s loudest voices.
Luka Urushibara (漆原 るか) — spelled Urushihara on some official English materials — is Mayuri’s classmate and the only son of Yanabayashi Shrine. Official copy is blunt: he carries every visual cue of a classical shrine maiden and is still a boy, wearing miko garb at his father’s suggestion. This primer stays spoiler-light on plot and honest about presentation, because RE:BOOT redraws that design in huke’s line and re-records Yu Kobayashi’s performance.
How the game wants you to meet him
Luka is earnest to a fault. He takes Rintaro Okabe’s Hououin Kyouma speeches at face value, which makes him both comic relief and a moral mirror: someone in Akihabara still believes the mad scientist bit. That sincerity is why Phone Trigger conversations with him feel different from Daru’s slang or Faris’s theatrics. You are not matching wits; you are deciding how roughly the lab is allowed to joke.
Read this page after Mayuri Shiina and Future Gadget Laboratory. Luka orbits the lab more than he founds it. Newcomers who binge only Okabe/Kurisu trailers often fail to clock why a shrine visit matters until Chapter 8 asks them to.
Reboot presentation
RE:BOOT’s E-mote sprites make posture and hesitation readable. Luka’s redesigned look is one of the places veterans argue taste: some prefer 2009’s softer sprites, some prefer the sharper 2026 wardrobe. Neither debate is a spoiler. What is new, according to launch-week clear reports, is a reworked closing stretch on Luka’s own ending — veterans who “already know” the 2009 scene should still watch it. Collectors comparing art books should use Edition Comparison rather than pausing on a CG in-stream.
Phone Trigger and frogs
Luka’s mail threads are where cute attachments hide. Chapter 3’s frog / Upa wallpaper chain is a trophy path, not an ending path: reply on the Gero-frog keyword and open every attached image. Missing an attachment can cost a completionist badge while the story cheerfully continues. That is the RE:BOOT lesson in miniature — Phone Trigger is social and inventory.
His story ending (“Link of Corruption and Rebirth”) splits at the Chapter 8 PhoneWave prompt. Skip the call to enter the route; make the call to continue the main line. Details and spoiler tables live on the True Ending Guide. This character page will not list the scene contents.
Respect and tone
Official text states Luka’s gender without treating it as a punchline, then lets Okabe’s chuunibyou do the punching instead. If you are sensitive to how visual novels handle that setup, go in informed: the route exists, it was rewritten at the end for RE:BOOT, and you can skip it the same way you skip Suzuha or Faris — by sending the continuation mail. Nobody on this wiki needs you to “prove” anything in comments.
How to use this primer in-play
- Learn the face and the shrine so later chapters do not feel like a new NPC dump.
- Keep one save before late-game PhoneWave experiments (Save Strategy).
- If you want every ending, budget Luka as the third character gate after Suzuha and Faris.
- Return to Characters Hub when a nickname (Lukako, etc.) flies by in voiced text.
Luka is the reminder that Future Gadget Lab is not only a found family of loud inventors. Some people enter Okabe’s world because they believed a lie kindly. RE:BOOT’s new animation makes that belief visible in the hands, not only in the font.
Frequently Asked Questions
Quick answers for observers playing RE:BOOT this week.

Japanese is 漆原. English materials mix Urushibara (classic) and Urushihara (some RE:BOOT pages). This wiki uses Urushibara in URLs and flags both.
When does Luka’s ending split?
Chapter 8, at the PhoneWave prompt. See the True Ending Guide if you want the mechanical table.
Do I need prior Steins;Gate knowledge?
No. The shrine, the uniform, and the earnest tone are taught in-play.
Who voices Luka in RE:BOOT?
Yu Kobayashi, returning with a full re-record like the rest of the main cast.
