Bibliography 3 authors last name, first name, last name, first name and first name last name

Question

Thank you in advance. So apparently I spent a lot of time editing Citavi styles to find out I cannot use them in LATEX :D

What I need is a bibliography with several authors being in this order: last name, first name, last name, first name and first name last name -> instead of "and" an "und" would be great (german)

what I get in Bibliography:

what I need it to look like (created with Citavi):

This should get you started, but you'll likely need more things customised. See the comments in the code for explanations.

\documentclass{article}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@book{doi+etal:1978,
  author = {Doi, Yutaka and Sano, Tetsufi and Tanaka, Itsua},
  date = {1978},
  maintitle = {Senkyo seido},
  maintitleaddon = {Das Wahlsystem},
  volume = {10},
  title = {Gendai chihô jichi zenshû},
  location = {Tôkyô},
  publisher = {Gyôsei}
}
\end{filecontents}

% set main language to German
\usepackage[ngerman]{babel}

% use German quotes
\usepackage{csquotes}

% use biblatex authoryear style
\usepackage[style=authoryear]{biblatex}
\addbibresource{\jobname.bib}

% new titleaddonpunct to use between maintitle and maintitleaddon
\newcommand*{\titleaddonpunct}{\addspace}

% don't emphasise title
\DeclareFieldFormat{title}{#1}

% place maintitleaddon in square brackets
\DeclareFieldFormat{maintitleaddon}{\mkbibbrackets{#1}}

% use a colon between sortname and title
\DeclareDelimFormat[bib,biblist]{nametitledelim}{\addcolon\space}

% use small caps for family names
\renewcommand*{\mkbibnamefamily}[1]{\textsc{#1}}

% redefine family-given/given-family so only last name is printed as
% given-family (this format is used by default for the sortname in authoryear
% style
\DeclareNameFormat{family-given/given-family}{%
  \ifnumequal{\value{listcount}}{\value{listtotal}}
    {\ifgiveninits
       {\usebibmacro{name:given-family}
         {\namepartfamily}
         {\namepartgiveni}
         {\namepartprefix}
         {\namepartsuffix}}
       {\usebibmacro{name:given-family}
         {\namepartfamily}
         {\namepartgiven}
         {\namepartprefix}
         {\namepartsuffix}}}
    {\ifgiveninits

         {\namepartgiveni}

         {\namepartsuffix}}
       {\usebibmacro{name:family-given}
         {\namepartfamily}
         {\namepartgiven}
         {\namepartprefix}
         {\namepartsuffix}}%
     \ifboolexpe{%
       test {\ifdefvoid\namepartgiven}
       and
       test {\ifdefvoid\namepartprefix}}
       {}
       {\usebibmacro{name:revsdelim}}}%
  \usebibmacro{name:andothers}}

% redefine maintitle bibmacro to use \titleaddonpunct between maintitle and
% maintitleaddon
\renewbibmacro*{maintitle}{%
  \ifboolexpr{
    test {\iffieldundef{maintitle}}
    and
    test {\iffieldundef{mainsubtitle}}
  }
    {}
    {\printtext[maintitle]{%
       \printfield[titlecase]{maintitle}%
       \setunit{\subtitlepunct}%
       \printfield[titlecase]{mainsubtitle}}%
     \setunit{\titleaddonpunct}}% replace \newunit
  \printfield{maintitleaddon}}
