Announcement, Special Program, and Version 4.5 Visuals

The Livestream Begins at 7:30 p.m. UTC+8

The Version 4.5 Special Program is scheduled for August 14 at 7:30 p.m. UTC+8.

For Indonesian viewers, that translates to:

• 6:30 p.m. WIB
• 7:30 p.m. WITA
• 8:30 p.m. WIT

Japanese viewers can watch at 8:30 p.m. JST.

The global broadcast will be available through Honkai: Star Rail’s official YouTube and Twitch channels.

This time, HoYoverse presents the program itself as broadcasting from an official livestream studio in Astropolis, tying the update presentation directly into the setting of Version 4.5.

The length of the program and its complete segment structure have not been announced.

The Story Continues after Planarcadia

HoYoverse describes the Version 4.5 story as a Trailblaze Continuance taking place after the conclusion of the journey in Planarcadia.

The wording deliberately leaves its chronology unclear. The new events may happen shortly afterward — or perhaps much further into the future.

That ambiguity makes the relationship between Planarcadia and Astropolis one of the major questions surrounding the update.

The Special Program will provide information related to Version 4.5’s Trailblaze storyline, although the quest structure, participating characters, explorable locations, and central conflict remain unrevealed.

In Japanese material, the new story is described as a 開拓クエスト・幕間, while Astropolis is called 千星シティ.

Robin • Summeretto Heads to Astropolis

Robin • Summeretto was previously introduced through the official “Variations on a Cosmic Tour” promotional series.

Her character material places her in Astropolis, enjoying its seaside weather while searching for inspiration for a new song.

She invites the Trailblazer to walk along the beach and listen to the sound of sea conchs, establishing a relaxed summer atmosphere around her new appearance.

The Special Program announcement once again directly associates Robin • Summeretto with the Version 4.5 vacation theme.

Her Japanese promotional name is ロビン・夏空の歌.

Complete gameplay information connected to Version 4.5, including her implementation, abilities, Light Cone details, and availability schedule, has not been revealed through the Special Program announcement.

Aventurine • Waveflair Joins the Summer Trip

Aventurine • Waveflair is the other familiar face prominently connected with Version 4.5.

His earlier promotional material describes him finishing a sponsored photo shoot before finally receiving time for a vacation.

Despite the relaxed setting, his introduction also hints at secret orders and another situation capable of pulling him into the center of trouble.

The Japanese version uses the name アベンチュリン・波と戯れる夏.

How Aventurine and Robin connect directly to the Trailblaze Continuance remains unknown. Their roles in the Astropolis storyline are likely to become clearer during the August 14 presentation.

What Has Not Been Announced Yet?

The title and main setting of Version 4.5 are now public, but most of the update’s gameplay details remain under wraps.

Still-unannounced information includes:

• the Version 4.5 launch date
• maintenance schedule
• complete Character Event Warp lineup
• rerun characters
• Light Cone Event Warp lineup
• finalized Version 4.5 character gameplay details
• seasonal events
• event rewards
• explorable areas
• new enemies and bosses
• new gameplay systems or modes
• total obtainable Stellar Jade
• Special Program redemption codes

Until the livestream airs, information not released through official channels should not be treated as the final Version 4.5 lineup.

Why This Matters

1) Astropolis is moving to the center of the story

After appearing in earlier promotional material, the location now becomes the setting used to introduce Version 4.5 itself.

2) The time gap after Planarcadia is deliberately mysterious

HoYoverse is not simply saying that the story continues afterward. It specifically raises the possibility that considerably more time may have passed.

3) Robin and Aventurine receive new summer identities

Their official promotional material already connects both characters directly with Astropolis rather than presenting the designs as unrelated seasonal artwork.

4) Most Version 4.5 details remain saved for the program

The livestream will be the primary source for the update’s story, events, Warp information, and new gameplay details.
