Is 'I Became Gasper Vladi In Highschool DxD' A Fanfiction Or Official Novel?

I recently found 'I Became Gasper Vladi in Highschool DxD' on a few platforms while browsing for fanfics. Webnovel has it listed under its fanfiction section, though you might need to dig through their tags to find it. Scribblehub is another solid option—it's free and has a decent search function. If you prefer downloadable formats, Archive of Our Own (AO3) sometimes hosts similar works, though the quality varies. Just be warned that unofficial translations or adaptations might pop up on aggregator sites, but those are hit-or-miss with ads and formatting issues. If you're into the 'Highschool DxD' universe, checking out 'The Devil's Backup Plan' on Wattpad could be a fun detour while you hunt for Gasper's story.

The main antagonists in 'I Became Gasper Vladi in Highschool DxD' are a mix of supernatural factions and individual powerhouses that keep things intense. The Khaos Brigade takes center stage as the primary threat, especially their leader Cao Cao, who wields the Longinus spear. This guy's cunning and ruthless, exploiting Gasper's insecurities about his vampiric powers. Then there's Rizevim Livan Lucifer, a fallen angel with a god complex who literally wants to destroy everything. His manipulation of others and sheer destructive power make him terrifying. The Hero Faction within the Khaos Brigade also plays a major role, targeting Gasper for his unique Sacred Gear. These antagonists aren't just evil for the sake of it—they challenge Gasper's growth, forcing him to confront his fears and unlock his potential.

In 'I Became Gasper Vladi in Highschool DxD', romance definitely plays a significant role, though it's woven into the story's supernatural and action-packed framework. Gasper's character, originally a timid vampire in the 'Highschool DxD' universe, gets a deeper exploration here. His relationships are layered—there’s the classic will-they-won’t-they tension with human and supernatural characters, especially since his awkward charm contrasts with his hidden power. The romance isn’t just fluff; it drives character growth. Gasper’s interactions often blur lines between friendship and something deeper, like his bond with Koneko, which starts as camaraderie but hints at mutual affection. The series leans into emotional moments—protecting someone sparks confessions, or shared battles turn into lingering glances. It’s not all roses, though; his vampiric nature adds angst, like fearing he’ll hurt those he loves. The blend of sweet moments and supernatural stakes keeps the romance dynamic.

As someone who's read both the original 'Highschool DxD' and this spin-off, I can confirm 'I Became Gasper Vladi' takes a sharp detour from the main storyline. While it keeps the same supernatural school setting and some core characters like Issei and Rias, the focus shifts entirely to Gasper's perspective. The original plot about Issei's Red Dragon Emperor powers gets sidelined for Gasper's unique struggles with his vampire heritage and time manipulation abilities. Key events from the main series either happen off-screen or get altered significantly due to Gasper's interference. The power scaling feels more personal too - instead of world-ending threats, we get intimate battles where Gasper's psychological growth matters more than raw strength. It's less about following the sacred gear hierarchy and more about exploring what it means to be a half-vampire in this universe.

Gasper's power evolution in 'I Became Gasper Vladi in Highschool DxD' is one of the most compelling arcs in the series. Initially, he's this timid kid with barely any control over his Sacred Gear, 'Forbidden Balor View,' which freezes time but drains him instantly. As the story progresses, he learns to harness it without passing out, extending the duration from seconds to minutes. His vampire heritage kicks in later, granting him enhanced physical abilities and shadow manipulation. By the end, he's not just freezing time; he's creating localized time loops and even bending space slightly around him. The transformation from a scared boy to a confident fighter is as satisfying as the power growth itself.

From what I know, the latest season of 'Highschool DxD' (Season 4) ended a while back and currently, there are no concrete announcements of a new one. That being said, light novels of the series are still ongoing. So to answer your question, the anime adaptation may or may not be over but the series as a whole isn't.

I've dug through my brain and a few bookmarked anime pages before typing this, but I can't safely quote the name from memory without double‑checking the credits. If you just want the quickest, reliable route: open the page for 'High School DxD' on MyAnimeList or AnimeNewsNetwork — both list full cast credits (Japanese seiyuu and English dub actors). Funimation/Crunchyroll streams also show cast in their episode details or end credits if you want to hear the performance right away. As a fan who rewatched Gasper's shy, freeze‑up scenes more times than I'd admit, I always enjoy seeing how the Japanese and English actors interpret the same awkward pauses differently. If you want, I can pull up the exact names and which seasons/OVA they appear in next — I usually cross‑check the anime's own credits plus a database like ANN to be sure.

As someone who's dived deep into the 'Highschool DxD' universe, I can confirm 'Highschool DxD Shadow Sovereign' isn't a direct sequel or spin-off—it's more of a fan-driven expansion. The original series follows Issei Hyoudou's chaotic adventures, while 'Shadow Sovereign' explores an alternate timeline with a new protagonist, blending darker themes and fresh power dynamics. It borrows the same supernatural framework—devils, sacred gears, and all—but carves its own mythos. What makes it intriguing is how it reimagines familiar characters like Rias and Akeno in supporting roles, giving them different arcs. The tone shifts from ecchi comedy to gritty strategy, appealing to fans craving a mature twist. It's unofficial but respects the lore enough to feel like a shadowy cousin to the main series.
