A downloadable playable fanfiction for Windows and Linux

Version Out Now!

Kura5 is a non-canonical fan game for the Boktai series and it's successor, Lunar Knights. It's neither a full remake nor a sequel, but a remix of both familiar Boktai staples and new elements that seek to recreate the magic that we all loved from the series. Kura5's weather system knows where you are in the real world, so there's no need for a solar sensor. In-game events may even play out differently depending on if you play in darkness or in light...And that's just the start!

This game is still currently in development but we have a demo that contains the first few areas. Feedback and bug reports are always appreciated!


  • Play as two halves of an unexpected duo: Annie, the Solar Gunslinger, and Emil, the Vampire Swordsman!
  • Utilize their abilities in tandem to overcome a common enemy.
  • Weather Sync reflects the time of day and weather in the game with that of the real world!
  • The world and play changes based off of weather!
  • Play during the daytime and use the Pile Driver to purify the remains of Immortals with sunlight...
  • Or play at night and utilize vampire magic to eliminate your foe.
  • You can turn Weather Sync off and enjoy the game without need for an internet connection.
  • An original soundtrack containing tracks both familiar and new!

Windows PC Requirements

  • Windows XP Service Pack 2 or higher
  • DirectX 9 or higher GPU
  • 2.0 GHz Dual Core Pentium, i3, or higher processor
  • ~550 MB available hard drive space
  • 2 GB RAM
  • A functioning sun
  • Moon (optional)

Note that these are rough estimates. If you're not sure if your computer can run the game, try playing it on the "Fastest" setting on startup.

Thank you! We'll always move forward. 

reminds me of boktai :)


You may be excited to see some familiar faces in the game then ;)

very good this game, great work, thank you for the version for LInux, I'm already indicating to friends. : D


Thank you so much!

wanted to drop by and say this is an outstanding piece of work here, my only concern was the sol guns being your primary way of killin stuff at the start, but it was nighttime when I was playing, so I couldn't play much. Looks good, handles good  d-pad is a lil touchy when it comes to knocking on walls ( like, you get stuck on the wall un-intentionally ) but that's always been a boktai thing. 

I told everyone I know about this, can't wait to sink into it while my sun's out ;3

Thank you! 

You will get another character later on to help you at night. And I really appreciate you telling your friends! 

I thought the characters felt a little stiff; like the end lag preventing movement on shooting Annie's gun especially was a little much for me, and seeing as how you can cancel any lag by lock on spamming or by just rolling away anyway I don't see a reason for its existence... 

UH BUT OTHERWISE - BRILLIANT??? I LOVED this. Anything Boktai brings joy to my heart and it helps that this was a pretty quality experience. I for some reason didn't expect to really care for the new cast, but any interaction between Annie and Emil was immediately made entertaining and had me smiling for miles. I love them.

AND DUDE when at the very end in the train car - even as basic as it was - A BOKTAI BLOCK PUSHING PUZZLE appeared before me I freaked. Boktai2 was KING on those, and yal better not sleep on the block puzzles! I need them!!!

I fell into the floor and got stuck once, and the music stopped playing at one point, but I feel yal know you are doing and everything will get polished up as we go on. Good stuff!!!

Oh gosh thank you so much! This is some great feedback.

Do you have any other examples of the characters feeling stiff? I can see about sending annie and emil to the chiropractor.

The stiffy-ness mostly just stemmed from the attack animations, really. Like basic movement and rolling I was pretty okay with. Now that I replay it though - I think Emil has the same amount of end lag after his sword swings I could also do with less of. Also that screen shake when he attacks in general ahhh not too big a fan? Obviously you need some of this stuff; the end lag and the shakyness to make attacks feel a certain way, I just think maybe they could be slightly lessened?

Hmm some other random tangents... I had some problems swapping lenses when using my 360 controller's analog stick; presumably because it was accepting extra inputs or something when I moved the stick a direction and it just kept rolling over my desired lens. I was able to avoid this by either making reaaaally delicate stick inputs, or by just using the DPad for lens swappings. Something could prob be done about that. ALTHO I just now realized this issue seemingly doesn't exist if you play the game on Fastest with the lower framerate; so the FPS being increased on higher settings seems to be the prob

Also... really petty but... Boktai 2 had a sort button for its item menus... I long for it so much here... My item menus got so dirty and disorganized. Is there one and I just didn't notice it? 

Ok! I can't do much about Emil's sword combo, but the controls should have been tightened up a bit, and the frame swap issue fixed too.

Let me know if there's anything else you have in mind, thank you!

Nice demo, though I think Emil's Shadow Binding needs a bit better duration, his combo needs a bit less end lag, I found it easier to just use 1 attack, wait, 1 attack so I didn't combo, and you need to get more sun for your time(I was playing at Noon with WeatherSync off and was only getting 2 bars) I know its winter and all but still, it shouldn't be that bad, I mean I can get a good 3 or 4 from reality on Boktai2 in goodish weather right now so it feels wrong

Also loved some of the secrets, David Iroquois Pliskin was my immediate giggle, and at some point I might dig around for more then just the few readable graves

Oh yeah and there's some issues with hitboxes lingering too long, namely sometimes pools of darkness will keep striking you even if you get knocked away, and mummy explosions hurting even when the graphic fades, speaking of mummies, in Boktai the state of burning can actually stack, increasing the damage with each flame on them

Very impressive composition. I'll keep a close eye on it, the weather thing is very nice :)
