The story begins when high school student Kazuki Muto is killed one night saving a mysterious girl from a monster, only to wake up in his school dorm, believing it to have been a dream; however, he soon finds out that dream wasn't a dream at all when a giant serpentine monster attacks him and his sister. Tokiko Tsumura, the girl he saved, explains that the monster is a homunculus. Kazuki had been attacked and killed by it when he was rescuing her; however, she, feeling responsible for him, revived him by placing a Kakugane medallion in his chest, serving as a replacement heart.

The Kakugane, as Tokiko explains, is an alchemical device that, when activated, takes a certain form based on the Kakugane's user, forming a unique Buso Renkin. The Buso Renkin is the only thing that can destroy a homunculus monster. Using this, Kazuki creates his own Buso Renkin (the "Sunlight Heart," a huge lance). Along with Tokiko and her own Buso Renkin (the "Valkyrie Skirt," an execution scythe), Kazuki joins the fight against the homunculi and their master.

After reading the manga I was curious about it was adapted into an anime, and to my surprise it was. The manga gave me such nostalgic feel I had to add this 26 episode show to my watchlist. It may be alittle silly especially with anime nowadays, but as someone who enjoys classic anime (back when anime was in parts, dvds, or cable tv), this brought me back to a time where I where I genuinely enjoyed Shonen work.

When they first mentioned alchemy, I couldn't get FMA out of my head, but a great story otherwise. I really enjoyed the unique style of weapons ...

Busou Renkin was truly the average shonen experience.

There were cool fights, cool weapons, explosions and all you would expect when seeing an anime of this genre. There wasn’t anything unique about it but, it really got the job done and managed to entertain you for a long time without having to think about anything.

Story - 6

The story in this show is alright. The story was simple. Some normal guy named Kazuki is well… A normal kid. But he also gains the power of alchemy and this thing called a Kakugane which forms a weapon to fight with. His being a lance. There’s a bunch ...

Busou Renkin

An older Shounen title, which shows most of the usual shortcomings, but has also put something individuality at the table.

This Title comes straight to the point in the first episode and explains to the audience what this story is about and what system this world follows there. It is in fact nothing too earth-shattering, but a more pleasant introduction than in some other Shounen.

I quote the description "Together they have to stop the humunculi now" - unfortunately this takes up almost the first 12 episodes of the work, in which there are almost continuous battles that devour almost the entire episodes and really ...
