Billboard reports that Taiki Kawakami, Fuse and Mitz Vah's *Tensei Shitara Suraimu Datta Ken (That Time I Got Reincarnated as a Slime)* Comic Edition Vol. 33 hit No. 1 on the Billboard Japan Book Hot 100 chart released October 15.

It is the third time the TenSura manga adaptation has topped the tally. The debut also dethrones last week's leader, Daisuke Ashihara's World Trigger Vol.

30, which slides to No. 2 overall.

The surprise in the numbers is how completely the volume dominated its debut week. Billboard's chart data shows Vol.

33 landing at No. 1 in both brick-and-mortar sales and e-books, while still reaching No. 10 in e-commerce — a top-10 placement across three separate metrics.

The chart itself is a comprehensive ranking that combines physical books, e-books, subscriptions such as library loans, and social media buzz, tracking the week from October 5 to 11.

What makes the No. 1 debut notable to chart watchers is the company it beat. Per Billboard, Arslan Senki (The Heroic Legend of Arslan) Vol.

25 by Hiromu Arakawa and Yoshiki Tanaka debuted at No. 3, Welcome to Demon School! Iruma-kun Vol.

51 took No. 5, Grand Blue Dreaming Vol. 27 hit No. 6, Ichi the Witch Vol.

10 landed at No. 7, and BORUTO -TWO BLUE VORTEX- Vol. 9, Blue Box Vol.

27 and Laid-Back Camp Vol. 19 rounded out the top 10.

For a series that has been running since its light novel origins, logging a third No. The volume topping both physical and digital formats simultaneously suggests fans are buying the new installment in whatever format they can get it, rather than the franchise's momentum living in only one channel.

In an interpretive chart week, that cross-format strength is the detail outlets are highlighting.

While Japanese charts celebrate a slime, Comic Watch reports that Marvel's retro limited series X-Men: Outback reaches its fifth issue on October 21, 2026, priced at $3.99.

According to Comic Watch, writer Steve Orlando and artist Steven Segovia's series — set in the late-'80s Outback Era from Chris Claremont and Marc Silvestri — features Mojo debuting a new ratings smash, the MURDER VIDEO CHANNEL, with Longshot explaining that Cliffhanger, Mojo's Murder Video star, is his ex.

Comic Watch notes the five-issue series follows retro hits like Psylocke: Ninja.

30 holding No. 2 across brick-and-mortar, e-books and overall, per Billboard.

On the Western side, Tformers reports new cover reveals for Skybound's Transformers line from Robert Kirkman, Jason Howard, Mike Spicer and Rus Wooton, with Transformers #39 due December 9, 2026, following Megatron's Megatronus Rex reveal.

Between chart milestones, retro X-Men sagas and Energon Universe expansions, the comics calendar is crowded into year's end.
